The main field of galaxies in the Coma-Virgo Galaxy Cluster, centred on the Markarian’s Chain line of galaxies, including bright ellipticals Messier 84, 86 and 87. At upper right is the star 6 Comae flanked by the spirals M98, M99 and M100. At lower left is the group of M58, M59 and M60, with M89 and M90 above them at left of centre. M88 and M91 are above those at upper left. Numerous NGC galaxies populate the field. The collection contains a variety of galaxy types: giant elliptical as well as spirals, both edge-on and face-on.

This is a stack of 14 x 3-minute exposures, with the William Optics RedCat 51mm astrograph at f/5, and with the Canon EOS Ra at ISO 1250, on the Astro-Physics Mach1 mount, tracking but not guided. The field is 8° x 5°. Taken May 13, 2020 from home on a very clear moonless night. Despite the scope being out for a while before I started shooting, its focus shifted slightly during the hour of exposures as the night cooled, making the last exposures a little soft. All stacked and median combined in Photoshop CC as there were satellite trails in many frames.

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.
