Stephan's Quintett - NGC 7320 and friends

It is now for almost 20 years that I tried to take a deep and well resolved picture of this fantastic galaxy cluster. Bad weather, wind and other obstacles got in my way so this is only the second acceptable portrait (see the first one here as part of my earlier portrait together with NGC 7331) and the first really deep one. See that interestingly enough, this picture gets by far deeper than the first one which was taken from the same spot with the 6-inch-APO and a QHY268M despite being slightly shorter in exposure time.

Stephan's Quintett is a cluster of five galaxies (NGC 7317, NGC 7318A, NGC 7318B, NGC 7318C, NGC 7319 and NGC 7320C) in about 300 MLy distance. Surprisingly, NGC 7320 is obviously not physically linked to that group but stand much closer to Earth in a distance of around 45 MLy, hence probably being a member of NGC 7331 group.

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.
