M88, M91 (and friends)

Two galaxies for the price of one in this image. Messier 88 is a spiral lying ~60 million light-years distant in Coma Berenices. It has a 6.5 x 3 arcminute extent on the sky, meaning the upper end of true size is on the order of 120K light years in diameter (long edge). M91 is a barred spiral also in Coma Berenices. It is further away than M88, having a distance of ~63 million light-years. It's size is 6 arcmins x 4.5 arcmins, implying a true size slightly smaller than M88 at 110K light-years.

Both galaxies have well defined structure, and are imposed on a field that is littered with other smaller galaxies. Normally I would isolate each galaxy for its own closer view, but in this case, I thought the pairing looked better together. It's a nice field.

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.
