Markarian's Chain

This is an amazing collection of galaxies in the constellation Virgo, the "Chain" is just one section of the much larger Virgo Cluster. It's named after astrophysicist Benjamin Markarian, who discovered common motion of the galaxies in the early 1960s.

It wasn't easy to know exactly how to crop the image - I wanted to make sure the Chain was highlighted, but also wanted to include some of the cool galaxies around it.

I decided to go without a light pollution filter since conditions were very good, and this helped to minimize background color correction during processing.

Description: Went for a "softer" look in this version and tried to minimize blowing out the galaxy cores.

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.
