Ring Nebula in RGB (M57 with some IC1296)

After doing this in narrowband, I switched to broadband near a new moon, and got several nights. No luminance was taken, but a synthetic luminance made from the minimum of the R, G and B stacks. HDR Multi-scale was used on the synthetic luminance (not the RGB). I am happy to see some secondary halo, this was very strong in narrowband, but very dim here. I was pleased that you can see the bared galaxy IC1296 fairly clearly, plus some smudges all over the background which are clearly other galaxies (I debated not cropping so tightly to show more, but wanted to show the ring better). Because of those I did not try to de-emphasize the stars for fear of also losing some of those smudges.

I would welcome any criticism or advice.

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.
