Description

4 panel mosaic of M31. Not quite got the intensity or the panels correct (3rd year in a row) and I know the starless image isn't everyone's cup of tea but I quite like it. Taken over several days with 3 hours in each panel for L and 1.5 in each panel of RGB. Total integration of 30 hours. STars removed using Starnet in PI.

Description: Re-processed in APP. Think I've gone to the edge of the mosaic without the seams becoming too much. Not perfect but happier now.
