I'm still sort of feeling my way through post-processing methods, I may come back to this someday. But mostly happy with this version. Getting the data was painful, I threw away a lot of frames as the first few nights I attempted to image; the clouds were a major tease, and then we had a lot of wind. And had various technical difficulties with my equipment (failed ethernet port on the computer, mount losing its mind either on its own or from a power blip and slamming the scope into the mount on a failed meridian flip — I only saw the result, wasn't watching it when it happened). But got one really good night to finish off the series (where I got the bulk of my data, actually, and most of the best data — though not the very best, maybe, it was just a little hazy. But time makes up for that).

This is a difficult one to frame, and ultimately that's the thing I like least about this version; I would do it differently if (when) I do it again.

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.
