First Light with the Askar FMA180 Pro

 It was a good night to shake down a new setup ...

The forecast for Saturday night 5/10 was for intermittent clouds early on and clear skies after midnight. this forecast, coupled with the fact that there was a very bright 96% illuminated Moon up almost the entire night, made it easy to decide to shake down my Askar FMA180 Pro (click here to view a post about building this rig). The goal was to get everything working, an imaging would be a bonus. 

The process started well before dark. It began when the Askar FRA600 (on loan from a friend) was removed from the mount. I took the Pegasus Astro Pocket Powerbox Advance off the Askar FRA600 rings and installed it on the Losmandy Dovetail Rail that the Askar FMA180 Pro was installed on. I have three gutter spikes in the ground where I set up my mount for imaging. The mount was leveled, then the Askar FMA180 Pro rig was installed on the mount and connected all the cables (performing some cable management to tame the mess of cables). I connected everything to my laptop and verified that all the devices could connect to NINA, adjusting COM port settings as required. The telescope was then slewed to point at the tree line across the street so the Guide Scope and the Imaging Scope could be roughly focused. I also created the PHD2 profile for this setup and took darks for the guide camera. The mount was parked and covered with a tarp. 

At dusk, I came back out and uncovered the scope. The first order of business was to properly focus the Guide Scope. I used SharpCap to do this. Once focused, the mount was polar aligned. SharpCap was used for this too. The Guide Camera was disconnected from SharpCap and was reconnected to PHD2. Using the Calibration Assistant Tool, the mount was slewed to 0 declination and about 5 degrees from the Meridian. After calibration was completed, I ran the Guiding Assistant for 15 minutes and applied the recommended changes to the guiding settings. The Imaging Scope was focused by eye. I worked on multiple autofocus runs in NINA to optimize the autofocus settings. After getting the autofocus set up, I verified plate solving worked. So far so good. Dodged a few clouds here and there but everything progressed smoothly. So now what?

I started to search for imaging targets that would be a good fit for this wide field rig. The best option was IC 1396, The Elephant Trunk Nebula. I have imaged this target before with my 80 mm Refractor at 480 mm of focal length (click here to view the previous result for IC 1396). Unfortunately, this target did not clear the tree line until about 1:30 AM. Since this was the first weekend with nice weather this spring, we did a lot of yard work during the day and I did not want to stay up all night. Then it hit me, maybe this was the time to finally try the (Advanced) Sequencer in NINA. I had already download templates from Patriot Astro, but never had a need to try this functionality out. I modified the OSC template for my setup and did a quick test. It worked perfectly. I loaded in a Sequence to image IC1396 starting at 1:30 AM until about 4:45 AM.  Again, it worked perfectly! I woke up the next morning and the scope was parked, the camera warmed, and 55 subs were saved to the laptop's hard drive. I was worried the subs would be of poor quality due to the 96% illuminated Moon but was pleasantly surprised after processing the image. Having said that, if the opportunity presents itself to add more exposure time to this, I will! 

Here's the resulting image :

IC 1396 - The Elephant Trunk Nebula - first light with the Askar FMA180 Pro.

Processing:

All pre and post processing was performed in PixInsight. Pre-Processing: All subs were visually inspected with Blink and subs with issues were removed. All light Frames, Flats, Darks and Dark flats were loaded into WBPP. Linear Post Processing: Background extraction was performed with GraXpert followed by BXT (correct only). SPCC was used for Color Calibration followed by a full application of BXT. The Stars were removed using StarXT. Starless Linear: Noise was reduced with NXT. The image was made non-linear with HT. Linear Stars: The stars were made non-linear with Seti Astro's Star Stretch Script.

Non-linear Post ProcessingStarless: The Narrowband normalization Process was used to get the "SHO" look. Color, intensity, and contrast were adjusted with various applications of CT. Saturation was increased with CT. The Image blend Script was used to sharpen the image with a High Pass Filter. LHE was applied at 2 Kernel sizes an the Unsharp mask was applied. The DSE script was used to enhance dark nebula regions. Stars: Saturation was increased with CT. SCNR was applied and the Correct Magenta Stars Script was used to help with stars captured with a dual narrowband filter. CT was used to adjust contrast one last time. Final: The Stars and Starless images were combined with Pixel Math to produce the final image. 

What is it?

IC 1396 is a region of ionized interstellar gas and dust that contains smaller regions of concentrated gas and dust that appear as dark knots or globules in visible light images. The gas in the entire region is being ionized by the bright star HD 206267 in the center of the image. The Elephant Trunk Nebula is one of those concentrations of gas and dust. It can be seen rising from the bottom of the image. These areas of concentrated gas and dust, including The Elephant Trunk, are star forming regions. Young stars within The Elephant Trunk were discovered in 2003 using infrared telescopes.

An annotated image of IC1396

How Big is it?

IC1396 has a size of 170 x 140 arcminutes (1 degree is 60 arcminutes) on the night sky and is about 100 light years across.

How Far is it?

IC 1396 is located about 2,400 light-years (ly) in the Constellation Cepheus.

How to find it?

The constellation Cepheus is located near the bright signpost constellation Cassiopeia. Cepheus is a circumpolar constellation for observers at mid-northern latitudes and above. This means the constellation never sets. It is visible all night, appearing to circle the north celestial pole currently located near the North star, Polaris. to me, this constellation looks like a house with a disproportionately large roof. IC 1396 is indicated in the chart by the red rectangle just off what would be the ground floor of the house.

A Trio in Leo and a Bright Asteroid too!!

 Where Science and Art Intersect ...

Please excuse this deep dive into my personal motivations for astrophotography. It is important to understanding why I'm so excited by this image and its contents. 

I came to astrophotography as a visual astronomer. I got into visual astronomy due to my deep interest in science. I've had this deep interest in science most of my life. I've never been an artistically minded person (although both my parents had artistic talents). I have been involved in astronomy outreach for many years; and I get great satisfaction from sharing the cosmos with our community. Once smart devices (smartphones and tablets) started to become common place, I tried to use them as another way to share the experience at my telescope with more people. This is what lead me down the path of astrophotography. Joining the Buffalo Astronomical Association (BAA) specifically to learn how to take better pictures of space and to get access to better instruments. Somewhere along the way, this became a creative or artistic outlet that I wasn't consciously looking for. To be 100% clear, the pictures I take of space are "pretty pictures". A lot of effort is placed on enhancing the data to optimize it aesthetically (color, sharpness, contrast etc.). The Science is still an underlaying foundation, that never goes away, and is a fundamental part of the experience for me. For me, astrophotography is at the intersection of Science and Art, both make an essential contribution to the experience. 

The forecast for Tuesday April 22nd improved to indicate clear skies for most of the night. A trip to our club's observatory was not in the cards for a work night. After work, I came home and set up my rig. I had not imaged from home since October. I had to rebalance the telescope on the mount, as it had been removed during the intervening time. Setting up took a little longer than usual but was completed without any issues. Once it was dark enough, the telescope was polar aligned, calibration in PHD2 guiding software was performed, and the focus of the main telescope was confirmed, allowing for successful plate solving and autofocus routines. The target for the night was already determined to be the Leo Triplet. There was no Moon until early in the morning, Leo is well placed in the sky for many hours of imaging, and I liked the framing with the Askar FRA600 (still on loan from my friend) and the ZWO ASI2600MC Pro. I loaded the sequence that I created in advance and hit play. Everything went smoothly and I imaged until about 10:30 PM when at the Meridian. I did not take flats at start up as I knew the camera had to be rotated to get the framing I wanted. So, I came out at Meridian Flip and took my flats. Once completed, I resumed the sequence and went inside to go to sleep. I knew I would lose the target some time between 2:30 to 3 am. The sequence was set to stop capturing images around 2:50 am, park the scope, and warm the camera sensor. I got up the next morning and put my rig into the shed before work, putting everything away properly after work. I collected 150 2-minute exposures. The last 20 were in the trees. After viewing the exposures with Blink in PixInsight, I ended up with 126 usable exposures. This is the resulting image:


This image of The Leo Triplet was captured on 4/22/2025 from my backyard.

Now the exciting part (at least for me):

After processing the image, I noticed a faint streaked smudge. Having experience processing comets, I recognized that something had moved relative to the stars. When we stack an image with a comet with the image registered to the stars, we get a very similar artifact. See the images below to get a better view of the artifact and to see where in the image it is located. The first image below has two rectangles. The small rectangle was drawn around the area in the image containing the smudge/streak. The large rectangle is an Insert with a 2X magnification of the area is in the small rectangle. This was inserted with Seti Astro's Astromark signature and Insert Adder script in PixInsight. The arrow indicates the location of the smudge/streak. The second image is a crop of the insert.

My initial thought was that it must be an asteroid, and a bright asteroid too!! Now to confirm and identify the asteroid. The first step was to plate solve the image. PixInsight compares the stars in the image to a database and precisely determines the location. PixInsight refers to this as an Astrometric Solution. Once solved, another PixInsight tool was used to annotate the image (see What is it? below to see the annotated image). There it was Asteroid 8 Flora. I was very excited at this point! 

The insert shows the streaked smudge indicating an object that caught my attention. The small rectangle indicates the actual position in the image and the larger rectangle (inset is this area with 2X zoom).

A close up of the area in the insert. 

Now that the asteroid was confirmed and identified, I wanted to see how much it moved over the course of the imaging session. I opened the first and last individual subframes (subs) from the imaging session, Image 001 and Image 130 (images 130 to 150 were in the trees and were not useful). The first image was captured at 9:25 PM and the last usable image was captured at 2:33 AM. This is a duration of 5 hours and 8 minutes. This includes the time used to take flats early in the session. Only 126 subs were used to process the image due to image quality issues. That's why the integration time for the image is only 4.2 hours. I did some processing on the individual images to make them look more presentable. BlurXTerminator was used to make the star shapes better, NoiseXTerminator was used to reduce the noise, and the stretch from the Screen Transfer function was applied with histogram Transformation to permanently stretch the images. The arrows were added with Cosmic Photons' Draw Annotation script. The arrows indicate the position of the asteroid.

Image 001, the first sub captured. The arrow indicates the position of asteroid 8 Flora.

Image 130, the last usable image captured. The arrow indicates the position of Asteroid 8 Flora.

Here's an animated GIF to help show the motion.:

Processing:

All pre and post processing was performed in PixInsight. Pre-Processing: All subs were visually inspected with Blink and subs with issues were removed. All light Frames, Flats, Darks and Dark flats were loaded into WBPP. Linear Post Processing: Background extraction was performed with GraXpert followed by BXT (correct only). SPCC was used for Color Calibration followed by a full application of BXT. The Stars were removed using StarXT. Starless Linear: Noise was reduced with NXT. The image was made non-linear with HT. Starless Non-linear Post Processing: Saturation and intensity were increased with CT. Exponential Transformation was used to increase intensity. The Create HDR Image script was used to compress the core of the galaxies (mask was used). The Image Blend script was used (with high pass filter) to increase sharpness. Stars Linear: The Stars image was made non-linear with Seti Astro's Star Stretch script. Stars Non-Linear: Saturation was increased with CT. Starless: Intensity, and contrast were adjusted with various applications of CT. The Stars and Starless images were combined with Pixel Math to produce the final image. 

What is it?

The Leo Triplet is also known as the M66 Group. It is a group of three galaxies in the constellation of Leo. The three galaxies that comprise the group are: M65, M66, & NGC 3628. NGC 3628 is also known as The Hamburger Galaxy. A faint tidal tale can be seen emanating from the lower righthand portion of NGC 3628. There are many more galaxies in this image, feel free to zoom in and look for tiny faint fuzzies.

Asteroid 8 Flora is in this field. It is a large, bright main-belt asteroid.

An annotated version of the image. Note asteroid 8 Flora is located in the lower left of the image.

How Big is it?

  • M65 has a size of 9.8 x 2.9 arcminutes (1 degree is 60 arcminutes) on the night sky and is about 117,100 light-years in diameter. 
  • M66 has a size of 9.1 x 4.1 arcminutes (1 degree is 60 arcminutes) on the night sky and is about 86,400 light-years in diameter. 
  • NGC 3628 has a size of 13.1 x 3.1 arcminutes (1 degree is 60 arcminutes) on the night sky and is about 140,400 light-years in diameter. 
  • Asteroid 8 Flora has an apparent size of 0.1 arcseconds and is 136 km in diameter.

How Far is it?

  • M65 is located about 41 million light-years (ly) from Earth in the constellation Leo.
  • M66 is located about 33 million light-years (ly) from Earth in the constellation Leo.
  • NGC 3628 is located about 37 million light-years (ly) from Earth in the constellation Leo.
  • Asteroid 8 Flora is 1.688 AU from Earth or about 14.04 light -minutes. One Astronomical Unit (AU) is the average distance to the Sun (93 million miles). 

How to find it?

The Leo Triplet is an excellent target for visual observation or astrophotography. To find it the it: first find the constellation Leo which is very well placed in the sky during the spring in the Northern Hemisphere. find "the Sickle" or "Backwards Question Mark", which is the front of the lion. The bright star Regulus is the handle of "the Sickle". Then find the slightly less bright star Denebola which is the tail of the lion. Moving in the direction of regulus, Chertan or Theta Leonis, is the next brightest star. It marks the hind quarters. Now move roughly in the direction of Virgo to find Iota Leonis, the lion's back leg. The Leo Triplet is about halfway between Chertan and Iota Leonis but slightly "off-line" in the direction of Denebola.

Building a “Super” Wide-Field Imaging Rig.

Super Sizing my Field of View ...

I have been thinking about and planning my next Astrophotography acquisition for many months. At the end of last year, I made the decision build a “super” wide-field imaging rig. The initial purchase for this project was the telescope, an Askar FMA180 Pro. In addition to the telescope, I also purchased the Askar EAF kit for the FMA180 Pro, Player One Ceres-C Guide Camera, and SvBony 30 mm f/4 Guide Scope. I purchased both items from Astroworld Telescopes around the holidays. Astroworld is a new retailer for astronomy related equipment with a strong focus on astrophotography gear. The company was started around NEAF 2023 by Daniel Higgins. Dan is an astrophotographer himself and in my opinion, he truly provides excellent customer service. The plan is to pair Askar FMA180 Pro with my ZWO  ASI2600MC Pro (APS-C) One Shot Color (OSC) camera. Wait!!! Let me back up for a minute and get into why I'm heading down this path.



Why Build a “Super” Wide-Field Rig:

My current primary imaging rig is already somewhat wide-field. I use an Explore Scientific Essential Series ED80 Triplet Refractor with my ZWO ASI2600MC Pro camera. This telescope has an aperture of 80 mm, a focal length of 480 mm, and is f/6.  It is an entry level scope as far as quality goes, it has served me well but long-term plan is to upgrade and use this for visual observer. The 80 mm refractor will make a nice compliment to my 8" Dobsonian. 

This 80 mm refactor has been perfect for many targets (Orion Nebula, Western Veil Nebula, Eastern Veil Nebula, and many others. The next piece of equipment in my collection that has a wider-field of view (FOV) is my 50 mm lens (the Nifty Fifty) for my DSLR. This is quite a gap and has proven to be a limitation, especially when bright comets with long tails are visible, as was the case this past October. Additionally, I live in Western New York (WNY), not far from Buffalo, NY. The weather here is persistently cloudy, primarily due to our position relative to Lake Erie. Also, I'm very active in our local astronomy club's (Buffalo Astronomical Association) outreach activities, which results in losing some nights to outreach events. Factoring in life's other obligations, I get about one night of imaging a month (on average). This creates a real obstacle for going after mosaics to capture larger objects (entire Cygnus Loop, Heart & Soul nebulae together, etc...). 

I was looking for telescopes/camera lenses in the 135 mm to 200 mm focal length range. I narrowed my choices down to the Rokinon 135 mm lens and the Askar FMA180 pro. An astronomy pal has let me use his Askar FRA600 telescope while he recovers from shoulder surgery. I'm really impressed with the quality of the optics and the overall quality of the scope. Feedback on the Askar FMA180 pro from other members of my local club and members of the AstroworldTV Discord community helped me come to the decision to go with the Askar. I want to be clear; feedback was positive on the Rokinon lens was positive too. Overall, the Askar won out in my brain. The combination of the Askar FMA180 Pro and the APS-C sized sensor of my ZWO ASI2600MC Pro camera will give me a FOV of about 7.5 degrees by 5 degrees. Here are a few screenshots from the website Telescopius.com Telescope Simulator tool showing how some popular objects will be framed with this setup.



Equipment Needed for the Build:

The Telescope: Askar FMA180 Pro. 

  • An apochromatic sextuplet refractor 
  • 40 mm aperture
  • 180 mm Focal Length
  • f/4.5 Focal Ratio
  • New Purchase (Astroworld Telescopes)


Imaging Camera: ZWO ASI2600MC Pro

  • APS-C sensor (IMX 571)
  • color
  • 3.76 um pixels
  • integrated USB 2.0 Hub
  • USB 3.0
  • Shared with existing rig


Guide Camera: Player One Ceres-C

  • IMX 224
  • Color (a mono camera would be more sensitive, color is fine for this rig)
  • 3.75 um pixels
  • New Purchase (Astroworld Telescopes)


Guide Scope: SvBony 30 mm f/4 Guide Scope

  • 30 mm aperture
  • 120 mm Focal length
  • f/4
  • Helical Focuser
  • New Purchase (Astroworld Telescopes)


Other Items/Accessories:

  • Askar EAF Kit for the FMA180 Pro (New Purchase - Astroworld Telescopes)
  • ZWO EAF (shared with existing rig)
  • Pegasus Astro Powerbox Advance (shared with existing rig)
  • ZWO Filter holder (shared with existing rig)
  • Dew Strips 
  • Losmandy Style Rail to mount everything on 

Future Items:

  • Apache Case
  • Dedicated Pegasus Astro pocket Powerbox Advanced
  • Mini PC

Build Status and Next Steps:

The rig is pretty much ready to go. I need to attach the Pegasus Powerbox (currently on my main imaging rig). I will share my imaging camera and the powerbox between the two rigs until I can afford to buy another powerbox (1st priority) and camera. I haven't had first light yet. That probably won't happen until late May / Early June. We are currently in galaxy season, as I write this in mid-April of 2025. I will use the FRA600 or our astronomy club's Celeston 14" Edge HD to image if any opportunities arise. They will be better suited for galaxies and my friend's shoulder will heal and he will want the FRA600 back. Looking forward to a super wide-field take on Nebula Season this year!

Clear Skies!

October 2024: An Amazing Month for Astronomy - Part 2

Chasing Comet C/2023 A3 (Tsuchinshan-ATLAS)

Saturday 10/12/2024 - Lakeview, NY

Chasing comets is so much fun. My first experience trying to capture one photographically was Comet Neowise in July of 2020. I was pretty new to astrophotography, so my results were ok, but it was so much fun. Was waiting for a chance for a bright comet now that my skills have improved. The Astronomy community has been excited for Comet C/2023 A (Tsuchinshan-ATLAS) almost as soon as it was discovered. Even though predictions for this comet indicated it could be a good one, we all take them with a grain of salt. Comets are like cats; they both have tails and they do what they want. 

Saturday 10/12 would be the first chance for me to catch the comet in the evening sky, as the comet had traveled around the Sun and became an evening object on Friday 10/11. The weather was poor on Friday, but Saturday was clear all day with clouds coming in at twilight. Would the clouds stay away long enough to get a peak at the comet? Next problem, where to observe? I have a fairly decent western horizon if I go to the farm across the street from my house. Looking at planetarium apps, it was close. My son-in-law's parents have a home on Lake Erie. In fact, their backyard is on a cliff above Lake Erie. They were gracious and allowed me to set up my DSLR and tripod in their yard. I also had my binoculars and my son-in-law's father also had a pair of binoculars. We were treated to a beautiful sunset, but there was a heavy bank of clouds on the horizon. I was afraid the comet would be behind the clouds. 

Spoiler alert, my expectation of where the comet would be, specifically how high above the horizon, was significantly off. My expectation of when the comet would be visible was off as well. Their neighbor came outside and asked if we could see anything. We told him we couldn't see anything, so he went back inside to attend to his parental duties. Just as was about to give up, we noticed Venus. It was much higher and further South than I expected. Arcturus became visible as well. The comet was roughly between Venus and Arcturus in azimuth, and it was close to Venus' altitude. We renewed the search, and their neighbor returned. We took turns looking through the binoculars. I kept snapping photos with my camera in hopes the comet would appear to the camera sensor before our eyes could detect it. Lots of false alarms, wispy clouds, jet contrails, but no comet. My son-in-law's mother told us she was seeing something and to her it felt like the comet. We thought it was another airplane contrail. She was pretty adamant; I pointed the camera based on her description relative to the clouds near the horizon. Took a photo at 7:33 pm, there it was!!!

We took turns looking through the binoculars and I kept taking pictures. The comet got brighter, and you could make it out naked eye. We watched it go behind clouds, then reemerge. We lost it to the dense cloud bank on the horizon around 8:07 PM. I was shooting with my Ha modified Canon T6i, fixed tripod, Canon 50 mm lens (The Nifty Fifty), and an intervalometer (used as a shutter release). I was taking pictures at different settings, bracketing exposures, to ensure I captured the comet. 

Here's my best shot of the evening:

A photograph of Comet C/2023 A3 (Tsuchinshan-ATLAS) taken on October 12, 2024, from the shore of Lake Erie in Lake View, NY. The image, captured with a Canon t6i and a 50 mm lens, shows the comet with a bright nucleus and a distinct tail extending upwards into the twilight sky. The horizon is illuminated with a gradient of colors from orange to deep blue, indicating the time of sunset or sunrise. Silhouettes of tree branches and leaves frame the foreground, adding depth to the scene. The calm waters of Lake Erie reflect the colors of the sky, enhancing the serene and picturesque quality of the photograph.

Monday 10/14/2024 - Eden, NY

It was very cloudy on Monday 10/14 so there was no expectation of seeing the comet. I had to pick up something from the grocery store and noticed significant breaks in the clouds, especially to the west. After returning home, I ran across the street and snapped a photo with my iPhone. Could definitely make out the comet. Went back home and grabbed the tripod with the iPhone adapter and set up to see if i capture the comet despite the clouds. The comet was visible to the naked eye, and I moved around to try and capture a pleasing composition. Here's my favorite shot from that evening. Cool note: The Planetary Society reposted my photo on their Instagram!


A nighttime photograph of a farm in Eden, NY, taken on Monday, October 14, 2023. The image features a red barn with a silo and other farm structures. The sky is clear with some clouds, and Comet C/2023 A3 (Tsuchinshan-ATLAS) is visible as a faint streak in the sky. The foreground shows a gravel path and a grassy area illuminated by artificial lights.

Thursday 10/17/2024 - Eden, NY

The skies were clear on Thursday night, but the transparency was not good. The Moon was full and definitely had an impact once it rose above the trees. I had difficulty seeing the comet naked eye, no trouble with binoculars (10x50). I had two imaging set ups going. The first set up was my Ha Modified Canon T6i with Canon 50 mm lens on the iOptron Sky Guider Pro. The other setup was an iPhone on a tripod.

The comet C/2023 A3 (Tsuchinshan-ATLAS) is faintly visible in the night sky above a tall pine tree in the foreground. The background features a cornfield and a treeline, adding depth and context to the serene rural landscape.

Friday 10/18/2024 - Eden, NY 

No photos (yet) from Friday night. 
Our observatory director came over to my house to observe/image the comet. I had the same set up as Thursday night. Conditions were better. Comet was more visible with the naked eye. The nearly Full Moon definitely impacted views and imaging.  

Saturday 10/19/2024 - North Java, NY

Our local astronomy club, the Buffalo Astronomical Association (BAA), has our dark sky observatory on the grounds of the Buffalo Audubon Society's (BAS) Beaver Meadow Nature Center. We call our observatory the Beaver Meadow Observatory (BMO). The BAS asked us to open the observatory on 10/19 to support their Trick-or-Treat Hike event. We had several members show up with their scopes and we had the Celestron 14" Edge HD with the club's camera. We put my ZWO ASI2600MC pro on the club's Tele Vue NP101is (w/0.8 reducer). Both scopes ride on the Astro Physics AP1200 mount. Another member of our club's imaging subgroup put his dedicated astronomy camera on his 85 mm lens. We mounted this onto the NP101/14" Edge setup. 

The event was from 4 pm to 9 pm so we shared views of the Sun early in the event and then switched to Comet, Saturn, and other Deep Sky Objects. We also have a member (he's one of the hosts of the 7th Magnitude podcast) that gives star/constellation tours with a laser pointer. This was a family-oriented event. Lots of families, with kids (and adults) dressed up in great Halloween costumes. The Comet was the ... STAR ... of the evening. We helped visitors find the comet and helped a few that brought their own camera set ups. People were able to find the comet using their phones, but some were able to see it naked eye (just barely). We had computer monitors and TV screens in the observatory control room displaying the images we were capturing of the comet. This worked out great, as large groups were able to cycle into the control to get a view and ask questions. One of our members did not bring her scope with her so she used my 8' Dob to share views of Saturn. Saturn's rings are almost edge on. It was a great night and the weather was perfect!

I was able to process the data from the NP101 with my camera (see image below). Still working on the data from the 14" Edge HD. I tagged Tele Vue when posting the image of the comet with the NP101 and my camera on social media. They reposted my post on X (formerly Twitter). That really made my day!!

Saturday 10/26/2024 - Eden, NY

The forecast called for skies to clear around 8pm on Saturday 10/26. We had family over for dinner. I snuck out around 7 pm and set up my Ha Modified Canon T6i on the iOptron Sky guider pro. I also had the tripod with iPhone adapter. I captured images with DSLR using both the Canon 50 mm lens (Nifty Fifty) and the Rokinon 14" mm Lens. The comet was near the Milky Way core. I'm not really pleased with how the DSLR shots turned out. Here's an iPhone shot processed in Snapseed.

The comet appears as a bright streak in the sky, while the Milky Way is visible as a faint, cloudy band stretching vertically across the image. Below the sky, there is a landscape with a few illuminated buildings and trees, adding a warm glow to the scene. The stars are scattered across the sky, creating a serene and captivating view of the cosmos.

So that's probably it for now ...

The comet is getting dimmer and there are other targets I'll want to capture with the limited clear skies we get. Now that it gets darker earlier, we might go after the comet at the observatory at the beginning of an imaging session. We'll see. Chasing this comet was so much fun!! So many great experiences! Can't wat for the next one.

NGC 281 - The Pac-Man Nebula

 I wonder how many quarters I spent on Pac Man when I was a kid?

Sunday September 15th was forecast to be clear with poor transparency due to wildfire smoke and a bright Moon. Since I had a vacation day on Monday, I decided to go ahead and image. I setup with the Optolong L-eXtreme dual narrowband filter to help fight against the bright Moon. I started the evening collecting subs on another target that I had collected some data on Friday 9/14. Imaged that target until i lost it to the trees around 12:30 AM and switched to NGC 281. Struggling to get the result I want from the other data, so no post for now. NGC 281 is also known as the Pac-Man nebula as the shape resembles the protagonist of the famous video game from the 80's. I think the resemblance is slightly diminished by deeper exposures like this, as additional details are revealed. 

NGC 281, The Pac-Man Nebula from 9/15.

Processing:

All pre and post processing was performed in PixInsight. Pre-Processing: All subs were visually inspected with Blink and subs with issues were removed. All light Frames, Flats, Darks and Dark flats were loaded into WBPP. Linear Post Processing: Background extraction was performed with Auto DBE Script from Seti Astro followed by BXT (correct only). SPCC was used for Color Calibration followed by a full application of BXT. Noise was reduced with NXT. The image was made non-linear with HT. Non-linear Post Processing: Stars were removed with StarXT. Stars: Saturation was increased with CT. Starless: The Narrowband normalization Process was used to get the "SHO" look. Color, intensity, and contrast were adjusted with various applications of CT. Saturation was increased with CT. LHE was applied at 3 Kernel sizes. Unsharp mask was applied and MMT was used to increase sharpness. The DSE script was used to enhance dark nebula regions. The Stars and Starless images were combined with Pixel Math to produce the final image. 

What is it?

NGC 281 is an HII region in the constellation Cassiopeia. Like most HII regions, it contains emission nebulosity, dark nebulosity, Bok Globules, and an open star cluster (IC 1590). One of the stars in this open cluster, HD 5005, is a multiple star that is helping to ionize the gas, creating the emission nebula.

Annotated image of NGC 281.

How Big is it?

NGC 281 has a size of 35 x 30 arcminutes (1 degree is 60 arcminutes) on the night sky. It is about 41.5 light years in diameter.

How Far is it?

NGC 281 is located about 4,100 light-years (ly) from Earth in the constellation Cassiopeia.

How to find it?

It may be possible to view this object visually (I have never done so). I would suggest a nebula filter (like a UHC or H-beta filter) to improve contrast and make the nebula "pop" in the eyepiece.

NGC 281 is located near the bright star Shedar in Cassiopeia. If you draw an imaginary line connecting Ruchbah and Shedar, NGC 281 would be a little less than 1/4 of the way to Ruchbah, and a bit off the line (towards Andromeda)/

A Tiptoe Through the Tulip Nebula

 Target Number Two from Friday 7/26

So picking up from where we left off in the last post (click here). After taking flats with no filter to match my B150 exposures, I installed the L-eXtreme filter and took flats. Then slewed the telescope to the Tulip Nebula (SH2-101) in Cygnus. Started collecting subs at 2:40 AM and stopped the sequence at 3:57 AM due to the increasing sky brightness and immanent loss of the target to the trees in the West.  Sky conditions weren't great due to the smoke from the wildfires out west. I've settled on 180 sec as the default exposure time for imaging with the L-eXtreme. Here's the resulting image:

An image of SH 2-101, also known as the Tulip Nebula, set against a starry night sky. The nebula appears as a complex cloud of gas and dust, illuminated in shades of pink and orange with hints of white, resembling the shape of a blooming tulip. It is surrounded by intricate filaments of blue and orange nebulous matter that weave through the darkness of space. A bright star shines prominently to the right side of the nebula, adding contrast to the scene.
SH2-101, The Tulip Nebula

Something cool in the image:

Any Rush fans out there? Any fans of Black Holes? The star labeled as HD226868 in the annotated image below is the star that orbits the black hole Cygnus X-1! See if you can see a very faint arch starting from the label HD226868 and arcing back towards +35°20’. It is really subtle, but it is the bow shock created by one of the relativistic jets emanating from the black hole interacting a denser area of dense interstellar medium. Cygnus X-1 is one of the strongest X-ray sources detectable from Earth and the first X-ray source to be widely accepted as a black hole. Cygnus X-1's status as black hole was the subject of a friendly bet between Stephen Hawking and Kip Thorne.

A Smoky Sea Horse Nebula

 It was perfectly clear, except for the wildfire smoke!

Friday 7/26 was the second night of what turned out to be a string of 4 clear nights. That was the good news. The bad news was that wildfire smoke from out west had rolled in. It would be the only night I would have any chance of imaging, so when we got home around 10 pm, I set up and was collecting subs by 11 pm. The week before I tore down my setup. I removed the dovetail saddle on my EQ6-R pro and replaced it with an ADM Saddle that was purchased at last year's NEAF. I also replaced my telescope with an Askar FRA600 that is on loan from a friend. He is unable to use the scope for a bit and generously allowed me to borrow it. I did some cleanish skies last Saturday night and was able to get focused and verify everything was working. 

The first target of the evening was Barnard 150, The Sea Horse Nebula. The 61% illuminated Moon rose around 11:38 PM. I continued to image this target until a little after 2 am, when the Moon started to clear the trees and was impacting the image quality. I took flats, popped the L-eXtreme filter in the image train, took flats with that and switched to a second target for the session. That will be another story. I captured a total of 74 exposures at 2 minutes each. Hope to get more time on this object, as I believe this will improve the result. Here's the final image. 

A view of Barnard 150, a dark nebula located in the constellation Cepheus. Resembling the shape of a seahorse, this elongated cloud of interstellar dust and gas curves gracefully from its head in the top right corner to its tail stretching toward the bottom left. The nebula stands out against a backdrop of numerous stars, creating a striking contrast between the dark features of Barnard 150 and the surrounding celestial canvas. Colors range from deep browns to faint blues, highlighting the intricate details of this cosmic wonder

All pre and post processing was performed in PixInsight. Pre-Processing: All subs were visually inspected with Blink and subs with issues were removed. All light Frames, Flats, Darks and Dark flats were loaded into WBPP. Linear Post Processing: Background extraction was performed with Auto DBE Script from Seti Astro followed by BXT (correct only).

LHE was applied at 3 Kernel sizes. Unsharp mask was applied and MMT was used to increase sharpness. The Stars and Starless images were combined with Pixel Math to produce the final image. 

What is it?

B150 is a Dark Nebula in the constellation Cepheus. It is an interstellar cloud and dust so dense that blocks the optical or visible light behind it (from our point of view). 

An Annotated image of B150.

How Big is it?

B150 has a size of 60 x 60 arcminutes (1 degree is 60 arcminutes) on the night sky. 

How Far is it?

B150 is located about 1,200 light-years (ly) from Earth in the constellation Cepheus.

How to find it?

I'm not going to say this object can't be observed visually because I don't know. I've never attempted to visually observe this. Definitely not a target for beginners. Dark skies with excellent seeing/transparency would be required to have a chance. This object is about 1 degree in angular size, so a fairly wide field of view would be required.

This object is in Cepheus as shown in the finder chart below. B150 is between Cepheus and Cygnus as indicated by the solid red rectangle in the finder chart.

M8, M20, and friends from the farm across the street

 Imaging in the heart of the Milky Way ...

I have not imaged with my home rig for several months. Been imaging with the club's scopes at the observatory and life has been pretty crazy (let's not talk about the weather). Saturday 7/6 was no exception. Our club had a Public Night at our observatory. I couldn't attend due to a family commitment. Fortunately, we got home in time to do some imaging. I live in farm country and have reasonably good skies. Unfortunately, I have a lousy horizon due to the trees. So, I set up across the street in my neighbor's backyard. Their yard borders their farm fields, so the horizon is amazing. This allowed me to go for M8 & M20, something I could never get from my yard.

I got imaging so late; I'm calling this on a Sunday 7/7 image. I had to stop multiple times due to clouds. Ended up with just under 2 hours of data (114 subs at 60 sec each). Really pleased with the result. Especially for a target that is so low in the sky here.

An astronomical image showcasing three beautiful objects in the night sky. In the foreground, the Lagoon Nebula (Messier 8) exhibits intricate patterns of gas and dust, illuminated by young stars. To the left, the Trifid Nebula (Messier 20) displays its characteristic three-lobed structure, with dark lanes dividing regions of emission and reflection. Nearby, Messier 21 is a sparse open star cluster. The entire scene is a captivating blend of cosmic clouds and stellar clusters.
M8, M20, and friends from across the street from my house.

Processing:

All pre and post processing was performed in PixInsight. Pre-Processing: All subs were visually inspected with Blink and subs with issues were removed. All light Frames, Flats, Darks and Dark flats were loaded into WBPP. Linear Post Processing: Background extraction was performed with GraXpert followed by BXT (correct only). SPCC was used for Color Calibration followed by a full application of BXT. Noise was reduced with NXT. The image was made non-linear with HT. Non-linear Post Processing: Stars were removed with StarXT. Stars: Saturation was increased with CT. Starless: Saturation was increased with CT. LHE was applied at 3 Kernel sizes. Unsharp mask was applied and MMT was used to increase sharpness. The Stars and Starless images were combined with Pixel Math to produce the final image. I ended up with 2 versions one bright image and a darker version. I liked elements of each, bit was not totally satisfied with either. I ended blending both images (70% dark with 30% bright) to get the final image.  

What is it?

There is a lot going on in this image. The scope was pointed into the heart of the Milky Way. Going to focus on the three Messier objects in the image. 

Messier 8 (M8) The Lagoon Nebula. M8 is a large star forming region, some dark nebula, and a star cluster. This is giant glowing cloud of interstellar dust where stars are forming and have been formed (the star cluster).

Messier 20 (M20) The Trifid Nebula. M20is a unique combination of a star cluster, emission nebula, dark nebula, and a reflection nebula. It is called the Trifid nebula due to the tree lobed appearance.

Messier 21 (M21). M21 is an open star cluster located near M20. This is a relatively young cluster at about 4.6 million years old.

An annotated image of M8 & M20.


How Big is it?

M8 has a size of 9o x 40 arcminutes (1 degree is 60 arcminutes) on the night sky. It is 113.6 light-years (ly) in diameter.

M20 has a size of 29 x27 arcminutes (1 degree is 60 arcminutes) on the night sky. It is 43.9 light-years (ly) in diameter.

M21 has a size of 14 arcminutes (1 degree is 60 arcminutes) on the night sky. It is 20 light-years (ly) in diameter.

How Far is it?

M8 is located about 4,300 light-years (ly) from Earth in the constellation Sagittarius.

M20 is located about 5,200 light-years (ly) from Earth in the constellation Sagittarius.

M21 is located about 3,900 light-years (ly) from Earth in the constellation Sagittarius.

How to find it?

The lagoon is naked eye visible in dark sky locations. All three objects are located in the constellation Sagittarius, which is low in the South for Northern Hemisphere stargazers in the summer. Find the Teapot, they are located above (North) of the Spout of the Teapot.
