NGC 7331 and the Deerlick Group
The NGC 7331 galaxy group, better known as the Deerlick group, consists of NGC 7331 (10.2),the main galaxy at 40 million light years distant, and NGC 7335 (14.5), 7336 (15.6), 7337 (14.5) and NGC 7340 (15.4). These smaller galaxies are known as the fleas and are more than 300 million light years away. There are many fainter galaxies in the field. Some of them aren’t shown on the chart (below). The group was imaged at Transit Dreams Observatory on October 20, 2017. Capture data is below.
