NGC7331 Group or the Deer Lick Group

NGC 7331, also known as Caldwell 30, is an unbarred spiral galaxy about 40 million light years away in the constellation Pegasus. NGC 7331 is the brightest galaxy in the field of a visual grouping known as the NGC 7331 group of galaxies or the Deer Lick Group. In fact, the other members of the group, NGC 7335, 7336, 7337 and 7340, lie far in the background at distances of approximately 300-350 million light years and are often called the fleas.

I processed the galaxies separately from the stars. This allowed me to really stretch and push the detail in the galaxies without affecting the stars. Processing the stars separately allowed me to reduce them. Finally the 2 images are merged together allowing the many fainter galaxies to be more easily seen.

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.
