According to my records M57 is, by far, my most imaged deep sky object of all times. Not a year passed by without me having a go at it, sometime for no purpose at all. No surprise to find it here then. Attempted high resolution but I know that much better exists nowadays and even in my times it was good but not outrageously so. Be as it may, it is right and proper to find it here, in this graveyard of old glories...

The bulk of the luminance data (at full focal length of over 2 meters) was captured in 2005 and provisionally I used old (2004 vintage) RGB data. Following that I picked up the data again adding better matching RGB and H-alpha (blended in the R channel) data taken in 2008 (but at a shorter focal length) to create this final image (drizzled 1.5x).

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.
