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!

IC 1848 - The Soul Nebula - 6.8 hours in SHO (and a Change in Horses Mid-Stride!)

IC 1848, Better known as The Soul Nebula, is an emission nebula located 6,500 light-years away in the cancellation of Cassiopeia.

This image results from 6.8 hours of narrowband data collected with my Askar FRA400 Astrograph and my ZWO classic ASI1600MM-Pro camera on the nights of Oct 20 and 22 and Nov 23 of 2022.

The first two nights were collected using the IOPtron CEM26 mount, and the third night was collected using a brand new ZWO AM5 Harmonic mount. This was the first time using the AM5, and it did an exceptional job with tracking errors reduced by 400%!

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!
