Atlas meets the Coma Cluster
Comet Atlas visited a busy part of the Coma Berenices galaxy cluster in the early hours of May 9, 2021. The trio below the comet includes NGC 4314, 4274 and 4245 while tiny NGC 4286 and 4283 and larger 4278 form a line near bottom centre. Eleven 5 minute exposures were taken with a modified Canon XSi DSLR at ISO 1600 through a 4” Borg astrograph operating at f4.2 and were processed in ImagesPlus. The picture was cropped a bit from the full frame.
