NGC 7331 is a spiral galaxy in Pegasus, about 40 million light years distant. Interestingly, the central bulge rotates in the opposite directions of its spiral arms. The surrounding galaxies are all much further away, about 300 million light years, and also quite distant to each other. The "Deer Lick Group", therefore, is only a visual grouping.

I quite enjoy the look of this galaxy: It has a lot of structure and quite a few young star clusters that are easily visible. The surrounding, smaller galaxies are a pleasing composition.

This was my first try with a clear filter on the mirror-only RC8. I also took some L, but there was no discernible difference in FWHM. I had (very) slightly more signal with the C filter, so I kept using it. Not sure if it will earn a permanent place in my filterwheel.

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.
