NGC 6820 / HSO w/RGB Stars

This is the result of a month long project using my new Antlia ALP-T filter and my 12" f5 newt. All the data was processed in APP extracting Ha, OIII and creating a synthetic SII. Color mapped in Pi for the HSO colors of the nebula. I used my L-Pro to collect shorter exposures for closer star colors and PCC them in PI. Created an RGB star layer and added them into the HSO starless image then did a final tweak or 2 in Gimp.
Star layer was manually stretched for desired star size.

I'm playing with 2 more versions, an SHO and HOO for fun and will post if I like them enough. I've also added the Ha channel for you to look at as well. I'm not a fan of looking at monochrome images but I felt this was a very clean image and I used it as my luminance as well for sharpening.

I hope you like the results.

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.
