Coma Berenices Asterism with NGC4571 and M91

A visual treat in Coma Berenices, highlighting two Virgo Cluster galaxies: the barred spiral M91 at 63 +/- 16 Mly distance and central spiral NGC 4571 (58 +/- 11 Mly), aligned with a colorful asterism of nearby stars of our Milky Way consisting of:

Double star HD109942 (brighter yellow), visual magnitude 7.21
Double star HD109983 (central red), m8.77
Star TYC 881-803-1 (blue), m9.23
Star TYC 881-860-1 (dimmer yellow), m9.58

...besides a bountiful bonanza of background galaxies.

This FOV caught my eye while I was doing a mosaic of the Markarian Chain last year (https://www.astrobin.com/d0iu7p/) and these subs have been languishing on the hard drive since then.

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.
