Description

The light frames from last year have been integrated and re-processed from scratch in PixInsight. AutoColor script was used for the color calibration.

The raw data is not particularly good. The autofocus worked very unreliably back then. Deconvolution has been able to restore some resolution, but still the details of the galaxy are rather blurred. Nevertheless I think that this image shows more details, especially in the far half of the galaxy.

Revision B has been annotated using SIMBAD catalog.
