Trifid nebula in an ocean of stars

Revision title: Red histogram

An *old* data set from DSW. Was actually a gift from the hosts to pass the time as the pandemic was in full effect. I spent 3 (kind of agonizing) days processing this. I'm quite terrible at getting stars the way I want them to behave since I don't like to mess with masks too much, and in a field this deep it was troublesome. I stared at so many examples of what other great astrophotographers have done with data of M20 of this caliber, and I seriously disliked this even after 3 full attempts of non-linear processing. Luminance was smoothing out the Ha blend I did in linear state by a lot, and I basically had to figure out a better way to stretch my luminance. In the end, using the GeneralisedHyperbolicStretch script for Pixinsight helped out a bit. I'm still not totally in love with it, but it'll do. Anyway, a big thanks to DSW for providing this data, always a pleasure to use their setups. Onto more painful data sets!

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.
