Description

This was difficult to acquire and difficult process.

I tried on 3 nights to get enough subs to process, and the first two nights we had high clouds, and some very poor seeing which resulted in a lot of subs thrown away. The third night was great however, hence over 9 hours of integration time

I made over a dozen masks to try and draw out the much fainter ring around the perimeter. I'm still not happy with the stars, but I'll post this for now. I have a dual boot machine (Kubuntu/Windows 11) and for this image I processed it using the  Kubuntu version of PI. Maybe I'll go back and reprocess under Window11 just so that I can use Starnet2, which isn't available in the Linux version. Meanwhile, this is the best I could achieve
