The Deer Lick group, the Stephan’s Quintet, and a bit of IFN

Three years ago, and three months after getting my first astro-camera, I imaged this field (https://www.astrobin.com/h0eb3e/) with RGB filters from my backyard. Knowing nothing better, I did not collect L data at all. But in the last month I revisited this target and decided to go as deep as my sky and patience would allow. I ended up adding more than 36 hours of L, more than twice the time I had spent on RGB in 2021. The resulting LRGB combination has very little to do with the original image, in detail, smoothness and depth. It shows some interesting tidal structures around some of the galaxies of the Quintet, and around NGC 7315. It even shows some tendrils of the Integrated Flux Nebula (hover the mouse pointer on the image to see it in the starless version), something I believed to be out of the realm of possible from Bortle 7.

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.
