NGC 7331 is an unbarred spiral galaxy some 40 million light years away in the constellation of Pegasus. It was discovered by William Herschel in 1784. NGC 7331 is the primary element in a visual group of galaxies sometimes referred to as the 'Deer Lick' Group (named by an astronomer who observed them at a site in the Deer Lick Gap in North Carolina).

Stephan's Quintet is a visual grouping of five galaxies first observed by Édouard Stephan at Marseille in 1877. The galaxies are NGC 7320, NGC 7319, NGC 7318, and NGC 7317. NGC 7320 is around 39 million light years away and forms a foreground visual element of the quintet. The remaining four galaxies are much further away at 210-340 million light years and have a physical association.

These galaxies were photographed between 30 August and 2 October 2022.

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.
