One of the longest “time on a single target” that I can remember doing, this is 5 hours of data on the Christmas Tree area, plus the Cone Nebule and some of the fox fur area. Its still quite noisy, probably due to some high cloud passing through or some othere excuse (hence why its all a bit “soft”). There are also at least 2 column defects in the full size image, so need to work out how to process them out, or move over to the M25C (and fix the dewing on the external nosepiece glass).
Anyway, here is the final image. I may look at getting some Ha data on this in the near future, and add that into the mix.
