Description

Closeup of Bode's Galaxy. I cropped in a bit to give a square aspect ratio, even though the 294 is a 4/3 sensor. I didn't have enough integration time (only 16.5 hours) to really pull any IFN out of my Bortle 7 skies. Holmberg IX its just barely resolved - again only 16.5 hours. This is a straight LRGB integration - no Ha filter enhancement. All of the post processing was done in PI. I tried to bring out as much of the detail as I could without potentially inventing what isn't actually there. I used a lot of incremental, small stretches and multiple different masks.

The stars suffer from some CA, but that's a "feature" of the Celestron 0.7x reducer .
