Trifid nebula M20 - Atria Team Chile

From ATRIA observatory with DeepSkyChile in Chile:
ATRIA Team composed of 6 members : Olivier, Fabien , Frédéric . David , Julien , and myself ;-)

The CDK17" gives a lot of details, I kept only 275 subs from 352 taken in Luminance with FWHM below 2.3" .
It is the work to get nice and fine details !

And finally, I selected the 45 subs with FWHM better than 1.7" which give fine details of the nodules and dark clouds.

Don't hesitate to zoom at the centre of the Trifid to look at the dark cloud details

Red 30 subs@420s -15°C gain high
Green 17 subs@300s -15°C gain high
Blue 22 subs@300s -15°C gain high
Light 275 subs@180s -15°C, gain high

Total integration : 20h 30′

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.
