M61 galaxy and surroundings.

[from Wikipedia]

M61 has a visual magnitude of 9.7, itis one of the largest members of Virgo Cluster, and belongs to a smaller subgroup known as the S Cloud. The morphological classification of SAB(rs)bc indicates a weakly-barred spiral with the suggestion of a ring structure and moderate to loosely wound spiral arms. It has an active galactic nucleus and is classified as a starburst galaxy containing a massive nuclear star cluster with an estimated mass of 105 solar masses and an age of 4 million years, as well as a central candidate supermassive black hole weighing around 5×106 M☉ solar masses

In this field several galaxies are visible other than M61, the most evident are:

NGC 4292: a 12th magnitude Spiral Galaxy 31 million light years away

NGC 4301: a 13th magnitude Spiral Galaxy 64 million light years away

NGC 4255: a 13th magnitude Spiral Galaxy 94 million light years away

UGC 7422: a 14th magnitude Spiral Galaxy 92 million light years away

UGC 7411: a 14th magnitude Spiral Galaxy 103 million light years away

UGC 7387: a 14th magnitude Spiral Galaxy 124 million light years away

and many others appearing as faint dots...

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.
