M 56

Lucky imaging warm-up while it was getting dark. Captured in SharpCap 4.0. Live stacking with rejection of blurry frames, then saved to Fits and processed in Siril (the main steps in Siril are photometry (gives stars their correct color), histogram stretching (asin, then levels), and the new version does a very good job of background equalization. Then Photoshop masks, levels, vibrance, etc. By the way, shot without darks and flats.
