M57 - Ring nebula in Lyra

This image is comprised of 17.4 hours of integration time from my Bortle 5 back yard. 11.5 hours integration was devoted to Hydrogen-alpha to image the halo, while the rest was RGB exposures. The image is actually a 3-panel mosaic, with 85 % overlap of panels, just to make the image approximately square.

The sky background, the galaxy IC 1296, and the core of the nebula were processed in RGB mode with synthetic luminance made from RGB subs. The halo and the star shapes (and star colors) were all derived from H-alpha (as luminance) with HGB for color channels.

It is rare that I can get 17 hours of integration on any object here in upstate NY, but there was an exceptional run of clear nights, and I was able to leave my imaging equipment outside without fear of rain for one week. It was great to image for so many nights in a row without setting up and aligning the 'scope every time.

The "A" revision is for those who like brighter / more saturated colors.

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.
