The Coma Cluster

This represents nearly 40 hours of data captured over six nights. I originally wanted to get to 100 hours but the career got in the way and now spring is over. Might try to hit 100 hours next year.

I've always been in awe of the Hubble Deep Field and wanted to try my own. Coma Cluster was a great place to start. I feel like I can start seeing some dim IFN and even maybe some sort of trans-galactic structure in the background. Need a lot more intregation time to know for sure.

Most of the nights had somewhat poor seeing, I feel like I could definitely get more detail on some of the tiny background galaxies if I avoid low desert spots in the Mojave.

Processing was pretty straightforward. I was pretty strict with subframe selector throwing out less than stellar subs, as I had plenty of data.
Spent a lot of time with deconvolution on the luminance channel to tease out more detail.
Combine with RGB data, stretch and do a few different sharpening/noise reduction tricks to get as much as I could out of it without going too far overboard.

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.
