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!

Messier 101 Supernova SN2023ixf ~3 Hrs in LRGB - Yet Another Supernova Shot - But This One Is Mine!

With the recent discovery of a bright supernova in the well-known Messier 101 - The Pinwheel Galaxy - a lot of astrophotographers have been going out of their way to grab an image of this galaxy during this event.

As a result, there are many - probably TOO many - images of this going around.

So why take an image myself? Is it because I think I can do better? NOPE! After all, I shot this on a widefield scope not suitable for galaxies, and I ended up shooting through smoke and with too little integration. So why do it?

Well - I wanted my own image of this event- and I wanted an excuse to explore what supernovae really are - after all - here I am looking at one!

So this posting will delve into this topic….

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 - 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 97 - The Owl Nebula and Messier 108 - The Surfboard Galaxy - 4 hours LRGB

Messier 97 - The Owl Nebula and Messier 108 - The Surfboard Galaxy - 4 hours LRGB

This imaging project captures two messier objects in the same field of view!

Messier 97 is a planetary nebula better known as the Owl Nebula.

Messier 108 is better known as the Surfboard Galaxy.

This image resulted from just under 4 hours of LRGB exposure. It was shot on my William Optics 132mm Plaform after being upgraded with a flattened/0.8X Reducer and a new ZWO ASI12600MM-Pro camera.

This image was the first project I have been able to do in 2023 and was taken on two nights when the Jet Stream pushed the Smoke Plume from the Alberta Wildfires to the south of us. But this image still suffered from smoke effects!

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

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….
