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 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!

Messier 81/82 Wide Field: 3.5 hours LRGB - A Failed Quest for IFN!

Messier 81/82 Wide Field: 3.5 hours LRGB - A Failed Quest for IFN!

I decided to try using my widefield Askar FRA400 platform to image the region around M81 & M82 to try and capture IFN (integrated Flux Nebula). This effort failed miserably! The resulting image was not too bad, but I was not able to get the kind of integration needed to capture this elusive feature! While this was a major disappointment, the resulting image shows M81, M82, and a third small galaxy NGC 3077 in a very nice part of the sky.
