The last (maybe, having difficulties processing Catalina) of my first light images with my AT72ED. I'm loving this scope! I used Kayron's new DSLR processing on it and I really like how it turned out. Not enough red IMHO but that could be due to the 132 minutes of light.

This is one of my favorite DSOs and I've always wanted to get it but not wanting to deal with mosaics as well plus had no time to do astrophotography last year.

Fully processed in PixInsight (except one mask)

Some details I couldn't get out which tells me I need some more light frames on this which may also bring out more of the red that I'm missing. But, it is an unmodded camera. :)
