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 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 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.
