And IV - hiding in plain sight

Andromeda IV must be the most imaged but at the same time least seen galaxy out there. It is right next to the Andromeda galaxy, but being a dwarf, and being very faint, it is rarely noticed. Here it gets centre stage, flanked by another dwarf galaxy (but this one with its own Messier number), and a star cluster.I believe it was an image or video by Adam Block that brought this dwarf galaxy to my attention. You would think that this galaxy is part of the Andromeda system, but in fact, the dwarf is about 20 million light years distant, well beyond, and not at all tied to M31. So, it shouldn't even have an "And" number. The galaxy was discovered by Sydney van den Bergh in 1972.

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.
