Description

After taking this image with my 4" refractor this spring I decided to make another attempt with my 12" SCT. After initial stacking I noticed some optical aberrations that were not there in previous images with this scope. I believe this was the result of incorrect backspace. This gave me an "opportunity " to learn some extra Pixinsight skills!
