NGC 4631, the Whale Galaxy and companion NGC 4627

NGC4631, the Whale Galaxy and Dwarf Elliptical companion NGC4627, in the constellation Canes Venatici. This is from raw FITS data. The total exposure is around 78 minutes (1182 x 3.97-second subs), not counting subs rejected by Pixinsight. There is a lot going on here, with a central Starburst region pushing gas out of the Whale. There seems to be a halo that surrounds both galaxies, but I couldn't pull it out of the background noise without really uglifying (a new word) the image. More exposure time needed to pull that "out of the weeds". A small magnitude 16.2 spiral galaxy, PGC3794315, is easily seen at the far left above center. The image is tightly cropped to hide some really noisy edges from field rotation and the neighbor's lights. Processed with Pixinsight. A deconvolution routine sharpened the galaxy a bit. Color correction and noise reduction along with some other tweaks finished the process. Bortle-6/7, L-pro filter, eV-1.

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.
