Hickson 7

This is a small galaxy group is located about 200 million light years away in the constellation of Cetus at a declination of +1 degrees. It is an unusual Hickson group in that all 4 galaxies have NGC designations. The galaxies are at a similar distance away, but still far enough part to prevent much disturbance in their disks. The top galaxy is a lenticular while the bottom 3 are spiral galaxies.

The brightest galaxy, 7a (NGC 192), is a 12.6 magnitude galaxy spanning 2.3 arc-minutes in our apparent view, which corresponds to a Milky Way like diameter of 130,000 light years.

The Hubble image is shown in Revision C. I did not include it in the mouseover comparison as I usually do, since the Hubble image only captured 2-1/2 of the 4 Hickson galaxies.

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.
