The bright galaxy Messier (M) 64 in Coma Berenices, aka the Black Eye Galaxy from its prominent dark dust lane around the nucleus. This is a stack of 16 x 6-minute exposures at ISO 1600 with the Canon EOS Ra through the Astro-Physics 130mm EDF refractor at f/6 with the 6x7 field flattener. Slight haze this night, April 12, 2021, added the star glows. The mount, the AP Mach 1, was autoguided with the MGEN3 autoguider applying a 5-pixel dithering shift between each frame. Alignment and stacking (with Median blend) of exported TIFFs was with Affinity Photo's Astrophotography Stack mode, as Photoshop did fail to accurately align this set, unusual for Photoshop. Development of raws was with Camera Raw, and editing was with Photoshop.
