M31, The Andromeda Galaxy HaLRGB

M31 is my kryptonite when it comes to my processing skills. I was rearraigning files and found some old data from 2021 that I gave up on processing due to mediocre results. I thought I'd give it another try now that I've added some new processing techniques to my repertoire.

For whatever reason, M31 gives me major fits with processing but the results were better than the first failed attempt so I decided to publish it. I'm looking forward to clear skies so I can go for a rematch with the shark!

Title: M31, The Andromeda Galaxy HaLRGB - Revised Color Processing

Description: I watched some videos by Shawn at Visible Dark in an effort to improve my colors. The effort seemed somewhat successful although the reds on the Ha might be a bit excessive. I might go back and dial down the Ha contribution in Pixel Math.

Title: M31, The Andromeda Galaxy HaLRGB - Reduced Ha level

Description: One more crack at this maddening target. This version used a tweak on the pixelmath formula to reduce the Ha contribution in an effort to get a better color balance. I'm hoping the thunderstorm that is over my house right now clears out in time to allow imaging of something new and less frustrating to process tonight!

Description: Yet another processing revision of my nemesis - M 31. Trying out revisions to my workflow while dealing with the cloudy skies in Arizona.

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.
