PGC 44959 (HCG 63d and others) – the galaxy to the right of PGC 44979

 

See the annotated image for the locations of these and various other galaxies.

 

Luminance – 18x300s – 90 minutes – binned 2x2

RGB – 18:15:15x300s – 90:75:75 minutes each – binned 2x2

Imaged over nine nights in April, May and June, 2023 at the El Sauce Observatory (Rio Hurtado, Chile) with a QHY 600M on a PlaneWave CDK24 at f/6.5 3974 mm.

 

These are Telescope Live (telescope.live/) “One-Click Observations.” Gold level members and above can suggestion these. This is one of my suggestions.
