M20 in SHO with RGB stars

Discovered by Charles Messier in 1764, M20 (Trifid Nebula) is a star-forming nebula located 9,000 light-years away from Earth in the constellation Sagittarius. This object is usually captured in LRGB or HaLRGB. I decided to make a SHO image with RGB stars to show details of its core which is usually not visible in broadband versions. Among other faint structures of the core, this image also shows the two finger-like jets emitting from the dust cloud from newly-formed stars.

These structures are visible in Hubble images but I was not able to see them in images captured by amateurs

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.
