Stephan's Quintet (Arp 319/Hickson 92 Galaxy Group)

Stephan's Quintet, a beautiful group of galaxies in the constellation Pegasus. This group contains five galaxies: NGC 7317, NGC 7319, NGC 7318A/B and NGC 7320C 210-310 million light years away and a less distant NGC 7320 at ~40 million light years. Stephan's Quintet was also designated as a group of galaxies Arp 319 in the Atlas of Peculiar Galaxies by Halton Arp.

This LRGB image was created using the data collected over a few nights in late August of 2022 with my mobile setup, the 10" f/4 Lacerta PhotoNewton and ZWO ASI294MM Pro camera riding on the Orion HDX-110 EQ-G mount.

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.
