Description

Started almost a year ago with some Ha data then finished in the past 2 weeks, not ideal with Moonlight interfering. The nebula is of course strongly emitting in Oiii and Ha which helps get some good data for the finished result. I had to discard about 30-40% of the RGB frames as they were slightly egg shaped which detracted from the finished result and adds more noise, must re-examine my guiding parameters!
M97 has three shells, you can just about see the outer shell in revision B which is a highly stretched version of the Oiii data.
Overall my best M97 to date despite some noisiness in the background, hope you like it
