The Eyes of Markarian’s Chain

It’s been a long time since I posted anything. Some equipment problems kept me from getting enough time to process anything for the last couple of months. I’m still playing catchup with images taken in May. This image was especially interesting to me because of the amount of galaxies that can be detected in this region. Besides the obvious galaxies visible in Markarian’s Chain, I was surprised by all the distant galaxies in the background. With a plate solve and catalog match I was able to identify approximately 3791 galaxies visible in this image with a limiting factor of magnitude 21. This astounded me and as a goal I wanted to make sure that I would keep as many of these galaxies visible during the processing of the image. It was a bit more difficult than I thought. Keeping the very faint signal of those distant galaxies and still capture detail in NGC4435 and NGC4438 (The Eyes) required very subtle and a numerous amount of masks. In the end, I’m quite happy with the results.

If your interested please take a look at the other post I made of this image with an annotated overlay showing all the galaxies found in my catalog search.

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.
