M31 Through LRGB Filters

Revision title: Now With Better Processing

M31 Has been a bit of a measuring stick for me over the course of my astrophotography journey. It's a deceptively tricky target with such high dynamic range. I'm happy with the amount of detail I captured in this image, but am perplexed by the strange color casts. I think it may have to do with how I'm doing dynamic background extraction. It's definitely something that I'll continue to refine the processing on, and when the clouds ease up, I'm looking forward to capturing more luminance data to help bring out more details.

Title: ... With Decon and More Aggressive Luminosity

Description: I tried out deconvolution for the first time. I like the detail that it added, but I don't like how much of the bright areas got "spread out" across the image. It also seems a bit noisier, so I'm not sure exactly how to combat that. I like the nebulosity to be nice and smooth, but this is a bit grainy for my taste. I also may have stretched the luminosity too far, but I just wanted to see how it would come out. Interesting bands of color, but I'm not sure what that's about just yet.

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.
