Title: M20 - Trifid Nebula

Description: I have been out of it for a while (got a new job which became my hobby for the last 9 months). And ofc now that I have a bit of time over holiday break, we have clouds in Southern CA. But anyone from this area knows, we don't complain about rain, so I decided to look through my data and do some reprocessing.

I was not very happy with my M20 that I have on astrobin: https://www.astrobin.com/full/exhv7y/B/ which was from when I was very much still learning how to do processing.

Spent a bit more time on it and am much happier with where it is now. Though I do have RGB stars so I think I will do another version with that (these are just the Ha star mask stars).

I am also still not super happy with my Hubble palette colors and I also feel there are stretching techniques that I want to learn about that do a better job with bringing out details in the bright areas as well as the dim areas. BUT, this is an improvement over the one I did in 2021 so I am happy!

Here are some details on M20:

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.
