Whale and Hokey Stick Galaxies

The NGC 4631 Group is a poorly defined group of galaxies, about 25 million light-years from Earth in the Coma Berenices and Canes Venatici constellations. It is one of many that lie within the Virgo Supercluster.

Members of the group are a spiral galaxy NGC 4631 (Whale Galaxy), brightest galaxy in the group, interacting galaxies NGC 4656 and NGC 4657 (Hockey Stick Galaxies), and dwarf elliptical galaxy NGC 4627, which is a companion of NGC 4631.

I imaged this galaxy a while ago and forgot to take flats, which worked for the RGB filters, but the L filer was not salvageable. I processed the RGB data and was pleased with the results, so here is the outcome. This target was also one of the earliest ones I imaged when I started this hobby, with a DSLR and a newt that didn't turn out to be AP oriented.

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.
