Revision title: Abell 85 Collaboration

Here's an image of LBN 576, also known as Abell 85 and the "Popped Balloon Nebula". This is probably one of the FAINTEST targets I've ever tried to image, but I figured I'd go ahead and post it since I took 235 subs @240s in Ha, Oiii, and Sii over 5 nights with my NP127is.
This faint supernova remnant is located in the constellation Cassiopeia at a distance of 9,780 light-years with a diameter of around 98 light-years and is approximately 10,000 years old.
This was not only a computer processing challenge....it took 3hrs 18m just to do WBPP, since each sub is 122MB with my ZWOASI 6200MM, but also a Pixinsight processing challenge, due to the faintness of the target.
Anyway, hope ya like it!

Title: Abell 85 Collaboration

Description: I wasn't happy with my processing of this data, so I reached out to Shawn Nielsen to help with it. This is mostly Shawn's processing (thanks Shawn).....he brought out much more of the Oiii and I just tweaked the star color and a couple other things.
Anyway, thanks again Shawn and hope ya like this revision!

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.
