M57 - Ring Nebula & IC 1296 in HaLRGB

Revision A - quick 3 hours acquisition & processing
Revision B - adding additional 6 hours of LRGB data (unfortunately data was worse as I hoped - outer shell is hardly visible - so improvement is not as good, hence also smaller FOV)
Revision C - added 4.5 hours of hydrogen alpha data, used the stars from first 60-sec acquisitions (RevA) as the 2nd night 120-sec acquisition had strange spiky shapes

As the data was not very good (bad seeing, a lot of humidity) the processing was quite though for me. I think I'd need at least 1 more night of LRGB and 1 more night of Ha data to improve image more.

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.
