Dumbbell Nebula in RGB + SHO (M27)

I imaged the Dumbell Nebula on several nights in June 2022 with almost every filter I had, then tried to combine them to present a color pallet that would show the structure of it without being too unusual (though this is not a 'true" color as your eyes might see it). I mixed these based on trying to highlight shape more than a typical pallet, first blending RGB to get a normal color plus normal stars, then a SHO variation using ForaxX, and blending the result (dropping the stars by using the square of the stretched version). The colors are a bit less saturated than I liked, but raising that made them just look wrong, so I settled here. In doing this I wanted to also emphasize some of the halo, which I was pleased to see I got in so little time from a Bortle 6 (pushing 7).

The Dumbell Nebula is about 1360 lightyears away in the constellation Vulpecula, and is a fairly bright planetary nebula at magnitude 7.5. it is thought to be somewhere between 9500 and 15000 years old.

I welcome criticism and suggestions in the comments or via PM.

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.
