Interesting target - with the added bonus of several more distant galaxies.
This was shot over two nights, neither of which was great for this low surface brightness galaxy: SQL 21.5, but seeing only 4" and poor transparency. Total exposure 5 hours 20 minutes, RGB only. Image scale 1.37"/px.
Processed in PI using PCC, a synthetic L made from all subs, with a touch of deconvolution to sharpen up the galaxy a little. Final fov approx 50' x 40'. Finished in PS.
ASA10N; Moravian G3-16200; DDM85A unguided.
