M20 during NAT 2023 edition - 19° altitude max

Acquisition made during french event NAT 2023 : Nuits Astronomiques de Touraine

During the event, I was mainly doing some EAA (a little) and some talks (a lot !)
Despite the very low altitude, 19-20° max in my region, M20 was one of my "dream target" 40 years ago so I wanted to try it in astrophoto

The meridian was at the beginning of astronomical dawn, and I could reach M20 for 1:30h each night, between 2:30am and 4:00am
We were lucky to have two clear nights with average seeing so at the end I had 32x14x16x16 x2minutes in LRGB and also 5x5mn in Ha
So after two nights, 3 hours total; I tried to get something out of it in order to have a "NAT 2023 version" of this beautiful nebula.

For the processing, I deliberatly let the outer Ha region with a low stretch : I did not have the signal for that and I like how the faint red glow enhance the central nebula
On the other hand, I push more the reflexion part in blue (even if I would have liked more signal there)

I need to get more B data (for the SNR of the reflexion nebula) and I will see also what I can do with time in Ha for an HaLRGB version

Given the seeing, the acquisition time and the altitude of this target, I am happy with the final result : I can try some very low altitude target and be happy with the result :-)
BlurXTerminator is a great help for that : it helps corrected the shape of the stars which are distorted with the atmospheric refraction.

I hope you will like it !

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.
