Imaging Projects

In this blog, I will share the results of all of my imaging projects. The newest will be at the top and the oldest will be further down the stack. Going back in time here is interesting - some of my early stuff was pretty rough - but I did not see it that way at the time - I was thrilled to get anything back that looked like an image! Hopefully, you will see how my work has progressed with time!

SH2-112 - A Diffuse Emission Nebula in Cygnus - 15.7 Hours in SHOrgb

Finally! Some clear nights and some new fresh from the universe photon data! This imaging project covers SH2-112 - A diffuse emission nebula located about 5,600 light-years away in Cygnus. This is the result of 15.6 hours of SHOrgb data. Not of lot of info is available about this beautiful object, but I find it fascinating to study!

SH2-101 - A Reprocess of The Tulip Nebula - 12.8 Hours in SHOrgb

This is a REPROCESSING PROJECT for Sharpless 101 (specifically Sh2-101) also known as the Tulip Nebula. This object is located approximately 6000 light-years away in the constellation of Cygnus (The Swan). This was a 12.8-hour integration with the AP130 platform using the ZWO ASI2600MM-Pro Camera.

I was able to significantly improve the image and am quite pleased with the improvement I was able to produce - but you be your own judge of this!

NGC 6888 - A Reprocess of The Crescent Nebula ~11 hours in HOOrgb

NGC 6888 - The Crescent Nebula is a famous emission nebula located in the constellation of Cygnus. This is a reprocessing project using image data first captured in September 2022.

SInce. I have no new data to process due to the wildfire smoke, I decided to use some new tools and processes to see if i could pull more details out from the O3 shell that surrounds the nebula.

THe resulting image show much more O3 detail - including some interesting convection cells towards the bottom of the nebula

Messier 102 - The Spindle Galaxy - 2.0 Hrs in LRGB - Still Shooting Through the Smoke…
Patrick A. Cosgrove Patrick A. Cosgrove

Messier 102 - The Spindle Galaxy - 2.0 Hrs in LRGB - Still Shooting Through the Smoke…

Messier 102, also known as NGC 5866 and the Spindle Galaxy, is located 50 Million light-years away in the constellation of Draco. Its diameter is 60,000 light-years, making it 2/3rds the size of our Milkyway even though it has about the same mass.

NGC 5866 is one of the two galaxies known as the Spindle Galaxy. The other, NGC 3115, is an edge-on lenticular galaxy located in the constellation Serpens.

This was another image from the lul in the smoke plumes from Alberta. Because of this, this image was starved for integration time and shot through some smoke still in the sky - so this image is not as good as I would like it to be. But - if you zoom in, you can see a lot of detail in the galaxy's dust lane!

Messier 104 - The Sombrero Galaxy - 1.7 Hrs in LRGB - Too Little Time, Too Low in the Sky, Too Much Smoke…

Messier 104, also known as the Sombrero Galaxy, is a stunning sight in the night sky. Located in the constellation Virgo, this galaxy stands out due to its unique shape. With a bright central bulge surrounded by a flat disk of stars, it resembles a sombrero hat. It is estimated to be approximately 28 million light-years away from Earth and spans about 94,000 light-years across.

I have always wanted to shoot this target, but this project produced a result far below what I was shooting for as conditions were poor (smoke plumes), and integration ended up being a ridiculous 1.7 hours!

Surprisingly the resulting image is not that bad. It's not good, either.

It did better than expected because of its capable Camera. But at least I have a baseline for when I shoot this target again n the future!

Messier 57 - A Reprocess of The Ring Nebula - 14.7 hours in LHaRGB!

Messier 57, the Ring Nebula has long been a visual favorite of mine. This was a reprocess of data that was collected in 2022. Based on 14.7 hours of HaLRGB, this data showed the rarely seen outer shell. I wanted to see if I could improve on that image with advanced tools and techniques. Since the original image was published, I created a new imaging project for posting to contain both the old and the new versions in the collection.

Messier 27 - A Reprocess of My Dumbbell Nebula Data in SHO - (10.25 Hours)

This imaging project is not a recapture of data for M27 - the Dumbell Nebula. Rather it is an effort to reprocess old data using new tools and new processing methods to address some concerns I had about the original image - where I thought that the stars were bloated and unsharp, and that I thought I should be able to bring out more detail in the amazing outer gas shells that narrowband imaging shows for this target.

NGC 281 - The Pacman Nebula - 8 hours in SHO (Fighting a Strange Artifact!)

NGC 281, better known as the “Pacman” Nebula, is located 9,500 light-years away in the constellation of Cassiopea.

This was the second time I shot this target. This image is the result of 8 hours of narrowband data rendered in the Hubble SHO palette.

This data was collected on my Astro-Physics 130mm f/8.35 APO refractor, and a ZWO ASI2600MM-Pro camera - all mounted on my IOptron CEM 60 Mount.

This image suffered from a strange circular artifact that took the form of nested rings in the corner of the image. Dealing with this caused me to make my background sky a bit darker than I would have preferred, but I think the image has a certain amount of drama and pop because of it!

IC 1396A - The Elephant’s Trunk - 7.3 hrs in SHO (a Case of Virus Interuptus)

IC 1396A - The Elephants Trunk Nebula is located 2400 light-years away in the constellation of Cepheus. This is my fourth project involving this target - but the first where I used the newer generation ZWO ASI26MM-Pro camera and full narrowband data set at this image scale. My goal here was to collect about 15 hours on target. I only ended up getting 7.3 hours. My usual reason for missing my integration target is weather. Not this time. This time I was hit with a nasty virus and the worst cold of my life! I had to watch two precious clear nights slip away whilst I coughed and hacked away inside in misery….

NGC 6888 - The Crescent Nebula - 12.9 hours in HOOrgb

NGC 6888 - The Crescent Nebula is a famous emission nebula located in the constellation of Cygnus. This is my third time imaging this target, and this is clearly my best take on it yet! This image is the result of 12.9 hours of narrowband and broadband integration - all shot on my Astro-Physics 130mm EDT and a ZWO ASI2600MM-Pro camera, I shot this as a bi-color HOO image an dused RGB data stars in it. Extensive use of starless processing was used to get this result. See more details in the posting.

Messier 57 - The Ring Nebula - 14.7 hours in LHaRGB - Capturing the Outer Ring!

Messier 57, the Ring Nebula has long been a visual favorite of mine. It is also a target that I have shot two times before with poor results due to its small size. This time I wanted to try to do the best job I could, given the limitations of my current gear. I also wanted to get a really long integration. Finally, I wanted to add Ha data in an attempt to capture the red outer gas rings that are not seen visually and often not seen in the typical amateur images. While I ran into problems on the way, did pretty well in meeting my goals. See the full post for the entire story!

Messier 13 - The Great Hercule Cluster - 8.5 hours in LRGB - Super Sharp!

Messier 13 - the Great Hercules Cluster - is one of the finest examples of a Globular Cluster that can be found in our skies. It consists of a giant ball of 100,000-500,00 stars packed into an area 145 light-years across. M13 can be found between 22,000 and 25,000 light-years away in the constellation of Hercules.

This is a 5.6 8.5 hour integration in LRGB using my Astro-Physics 130mm scope the ZWO ASI2600MM-Pro camera. This is the fourth time I have shot this target and this one is clearly my best - displaying a remarkable sharpness in detail.

NGC 5907/5906 - The Splinter Galaxy - 8 hrs in LRGB

NGC 5907 -The Splinter Galaxy - is another example of an edge-on Spiral galaxy that displays significant dust lane detail across its middle. Its located 54.5 million Light years away in the constellation of Draco. This was shot with my Astro-Physics 130mm with the ASI2600MM-Pro camera. 8 hours of integration in LRGB. It was a real challenge to pull out the details from this very small galaxy.

M101 - The Pinwheel Galaxy in LHaRGB (11 hours)- a third attempt!

My third attempt shooting Messier 101 - the Pinwheel Galaxy. My first was in 2020 using an OSC camera and a two-hour exposure. Not bad for a first attempt. My second was in 2021 using an ASI1600MM-Prop mono camera. 15-hour integration! However many data problems and a very poor final results. This time around I am using my Astro-Physics 130mm with the ASI2600MM-Pro camera. 11 hours of integration in LHaRGB.

NGC 2359 - Thor’s Helmet in SHO ~only 2.5 hours!

NGC 2359 - Thor’s Helmet - is my first image of 2022. This image is the result of 2.5 hours of narrowband data - limited by weather and the fact that this target is very low in the sky for me and access is very limited each night due to trees on my property. I had hoped to gather more data but at this point, it is now too late in the year. So my challenge was to see what I could do with such limited data. detailed processing strategy and log provided!

SH2-115 and Abell 71 - 4.0 hours in SHO

This is the 10th and final image to come from a capture season that occurred this past November. SH2-115 is a large emission nebula located in Cygnus. This was the result of 4 hours of narrowband data integration taken with the Williams Optics 132mm FLT APO scope, the CEM60 mount, and the ASI1600MM-Pro camera.

NGC 7293, The Helix Nebula ~4.5 hours of LHaRGB: Dealing with “Bad Data”

This was my second attempt to capture NGC 7293 - the Helix Nebula - located in the constellation of Aquarius. This time I had high expectations as I was using longer integration times, a longer focal length scope, and a new generation ASI2600MMPro camera. However - LOTS of things went wrong with this capture and its data came out pretty compromised! Some intense image processing minimized the impact of these problems - but the final image falls far short of my expectations. A good example of what can go wrong!

IC 1848 - The Soul Nebula - Only 2 Hours of NB Data from an Abandoned Project

IC1848, known as the Soul Nebula, is located ~6500 light-years away in the constellation Cassiopeia. This is image was from an aborted project. I only captured 2 hours of NB data when the weather turned and I lost my shooting window. I had so little data I abandoned the project and did not even capture cal data for it! But I decided to use the data to test out a newly built image processing computer and was surprised the image tuned out better than I have imagined (at least it was not horrible!)
