Description

Maksutov for planetary nebula work? But of course, it only makes sense! A proof-of-concept trial-run for my Mak 180 as a deep-sky scope.  All went fine more-less but one thing I need to buy is a threaded connection for my imaging train (SW Mak's random thread diameter makes finding it a challenge).

Recently I was sort of happy I won't have to edit galaxy photos for a while but then I ended up with M27 and M57 which are high dynamic range targets and working on them was not at all easier.  These planetary nebulas is one of the areas where the new GHS routine really helps.

Integer resample for 3x3 binning in post-processing.  The resulting 0.9 pixel scale is about the limit of my seeing and guiding.  New mount on order since January....
