M57 - W/RGB Stars

Revision title: Central star

This is a wide field version of M57 in HOO with RGB stars. I processed all data with APP after extracting the NB data and color mapping it to HOO and then post processed in PI.
I processed the star color in PI after splitting channels and doing a PCC for star color accuracy. Used StarXTerminator with the PM on a thread that has been somewhat of a hot topic in the forums. This is where you pull luminance from your NB stars and add them back to your RGB stars and then use the formula in this thread if your interested. https://www.astrobin.com/forum/c/astrophotography/deep-sky-processing-techniques/an-excellent-method-of-blending-rgb-stars-with-a-narrowband-image/
Data was acquired from 9/1/22 - 9/15/22. I had so many acquisition dates that I just added each filter type and sub length and posted them on different days.

I processed this for the wide field and then cropped this image to zoom it in. In the next day or two, I plan to do a portrait version that I'll reprocess the data and will post it if I like the out come.

I hope you like it and I'm always open to comments good or bad.

Thanks for looking!

Title: Portrait

Description: Adjusted the brightness of the inter ring of the nebula to pull better detail. I know many will not like this, but I wanted to push my data to see how close I could get it to look like my favorite Hubble image (REV d) of this object. There is no question my version is not the Hubble, but it was fun, not to mention I learned a few things doing it.

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.
