| Description | This is a very rich galaxy-field. Besides the galaxy cluster that Arp labels, I counted 12 additional galaxies by eye. The Astrometry.net annotation is so cluttered that it's very challenging to read. Included as part of Arp 331 are NGC 383 (central galaxy), 379, 380, 382, 384, 385, 386, and 388. Additional galaxies within the field of view include: NGC 370, 373, 374, 375, 392, 397, 398, 399, 400, 402, 403 plus IC 1614, 1618, 1619. This means the annotation found at least 2 galaxies I didn't count by eye, presumably the IC galaxies (IC 1614 is 17th magnitude). This observation was part of the December 2023 Cloudy Nights EAA Challenge, which is why I observed it when I did. |
