At a distance of about 500 million light years, this cluster contains about 200 galaxies. It has no large galaxy at its core. Its largest member is NGC 6040 (Arp 122), the topmost, distorted spiral within the central galaxies. Besides Arp 122 it also contains Arp 172 (lower right), Arp 71 (vertical spiral in the center) and Arp 272 (middle below center).

On my first outing with the new kit, one after the other, the following things failed to cooperate: The EAGLE Wifi connection (good a router was lying around), the dovetail clamp (sh

ock...), the motor focuser coupling (so this is manually focused, no mask), seeing (went to 3"), clear skies (high clouds came up unexpectedly) and darkness (only 45' of astro darkness here currently). Bortle 4 helped a lot, though.

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.
