M57 - a life-ring

Revision title: Post-processed in Startools v9

M57 is a something of a ‘life-ring’ at this time of year, well at least an aid to keep us buoyant when the nights are short.

A simple colour snap, with short subs, and 17 minutes of integration. The ring nebula looks good in longer focal lengths, although narrowband helps to pull out even more detail.

Herewith two versions, Rev B (final) is post-processed in Startools utilising high dynamic range to tease some detail out of the ring, and a de-warping tool to improve the stars. Mouseover for the original, processed in Siril, and click for the annotated version.

Description: Using HDR to develop more contrast in the ring, a little colour saturation, and repair to the wonky stars gives this a better look.

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.
