NGC 7331 is the dominant galaxy in this field. It is the brightest member of the Deer Lick Group - consisting of NGC 7331 and the smaller galaxies NGC 7335, 7336, 7337, 7340. This is an optical grouping since NGC 7331 is much less distant (46 mly) than the other four (260+ mly). NGC 7335, 7337, 7340 are actually members of the physically associated group HDC 1198 (centered 268 mly distant). A 2012 paper, Giant Galaxies, Dwarfs, and Debris (GGADDS), identified satellite dwarfs associated with NGC 7331. These are identified as NGC 7331 A, B, C, and D. There are also a number of background galaxies in this field. These galaxies are identified in the annotated image. Horizontal FOV is approximately 38 arc minutes (0.87 arcsec/pix image scale on the full size image).

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
