NGC-7331 and the Deer Lick Cluster

Subject: NGC-7331 is a Milky Way-sized galaxy roughly 40 million light-years distant. Interestingly, the central bulge appears to rotate in a direction opposite the rest of the galaxy! The smaller galaxies in the Deer Lick cluster are a variety of types, roughly 280-350 million light-years distant.

Capture notes: All RGB, with a synthetic luminance, captured in the week after the new moon in August.

Processing notes: Standard RGB processing with PhotometricColorCalibration for color. I'm really enjoying the results PCC gives: generally much more natural than what I've been able to achieve with normal color calibration processes. One thing in this picture is fabricated, however, The three bright stars (in an upside-down triangle shape) near the top galaxy are clones of other stars in the image (in the synthetic luminance). The original stars were very bloated and I was unable to tame them with any technique that I know. I feel a little badly about manipulating the image that way, but they were otherwise very distracting. So, I hope you'll forgive me.

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.
