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!

WR 134 - A Wolf-Rayet Star Region In Cygnus- 15.5 Hours in SHO

This is the third and final Imaging Project resulting from data collected during a recent - and very rare for this year - clear string of nights!

This is WR134 - a Variable Wolf-Rayet Star located 6,000 light-years away in the constellation Cygnus. This is a very interesting and rich area of the sky with a lot of objects in view. This includes WR134, WR135, and WR137 - the very first Wolf-Rayet stars ever found. These stars stood out as they had broad emission lines in their spectra instead of just absorption lines typically seen in stars.. These stares are massive and hot and have short lives.

NGC 6914 - The Spider Nebula (my name!) - 14.5 Hours in SHOrgb

NGC 6914 - The Spider Nebula (my name!) - 14.5 Hours in SHOrgb

This is the second Imaging Project resulting from data collected during a recent - and very rare this year - clear string of nights!

This is NGC 6914 - a rich HII region located 6,000 light-years away in Cygnus. Typically shot in broadband RGB, decided to go after a narrowband version. This one resulted from 14.5 hours of SHOrgb data. The stars are broadband RGB, and the nebula is SHO Narrowband.

This object has no common name and I am proposing that we call it “The Spider Nebula!”

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!
