Abell 85 HA O-III

Seems to be the most heavily imaged Abell Object on Astrobin.

This supernova remnant known as Abell 85 and as CTB 1 is located in the constellation of Cassiopeia. It is in Abell's catalog of planetary nebulae but later determined to be a supernova remnant .

Complicated processing for me. Did not use the RGB. The color was obtained with the destarred O and HA and using the formula for Teal in O from Rob: OIII data to my green channel data at 72% strength and at 88% strength into blue. HA was R.

This was blurred and the L was from obtained the original HA and O destarred images added in PI using the Max function. The stars added back in.

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.
