In a haze of Hydrogen, M57 Ultra Deep field

In a haze of Hydrogen, M57 Ultra deep field showing it's layers of extended shell and background. Imaged remotely from Spain with the 12inch ASA Newtonian and ASI2600MM pro Roboscopes Pier 3. Exposure times were 2hrs in RGB all 60s subs, 6hrs of OIII, 180s subs, and 23and a half hrs of H-alpha all 180s subs.
Its worth zooming in to see the layers in the shell, I was quite surprised at the colour pallet that the OIII and Ha gave. Trying to pull out core detail in this is generally difficult on M57 due to its apparent size even more so on such wide field so rather than just do the ring itself I set out to see if there was any background H-alpha....

A comparison from my very first CCD image taken with a borrowed Meade LX 2180 from the Birmingham Astronomical Society and my very first CCD camera MX5 from nearly 30years ago....How things have moved on!!!!.

Thanks for looking

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.
