Description

Need more data but this is 4 nights imaging: Then subframe selection based on FWHM, Eccentricity and a weight function.
60 bias frames / night.

Total stack: 3810 x 1 sec (HO with L-Enhance) with ASI585MC
Total stack: 2741 x 1 sec (Color) with ASI585MC

Unguided with 10" TS-Photon in Bortle 5 at f/3

Processing with Pixinsight and deconvolution tools, TopasAISharpen (I know I overkilled it) and Photoshop Express to highlight the galaxy spiral arms structure.
Still need to fix the color aberations and halo's.
