The Coma Cluster of Galaxies contains about 1000 galaxies in an area of roughly 3x5 degrees on the sky, of which the central part is shown in the full field. The core is dominated by two giant cD ellipticals NGC4889 and NGC4874. Only a few spirals are found, a hint to advanced merging of the cluster members and high cluster age. The core seems to be embedded in a huge cloud of gas and dust that is visible in the image.

LRGB with Takahashi Epsilon 130ED and ASI1600MMP.

A crop on the core (marked as original or final), the full field (2.5 x 1.8°, version B), and an annotated version are shown.

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.
Dismissals 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.
