M20 Trifid Nebula in context

This started life as Panel 1 of a 6 panel mosaic, but after looking at this capture in Ha I was taken by the amount of nebulosity in the area and how M20 was linked through to M8. This HARGB is the outcome then of 6 hours of data using a Canon 60Da and a Ha6nm filter along with a couple of hours of RGB. Maybe one day I will finish the mosaic, but not this year.

the Ha version has been uploaded seperately

M20 is approximately 5.5 light years away and is primarily an emmission nebula (red) alongside and encompassed by a reflection nebula (blue). The "split" through the middle is a dark Nebula, just dust you cant see through, designated Barnard 85. Its in Sagittarius and when you look at wide field shots of this area it is embedded in a quite amazing Star field which I have never managed to process properly..

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.
