M100 started life as an attempt at higher resolution (at approx. 0.75"/px) at the lower declinations (read altitudes) in the spring of 2010. The results were, shall we say, a bit (a lot) disappointing... Clearly a refocus on lower sampling was required to achieve a better SNR. Which started off in earnest two years later piling on a rather largish amount of sky time. However not all was well as the seeing remained doggedly on the crappy side week in week out. Exhausted I called it quits. Fast forward to 2020. Looking at the what was produced back in 2012 the image wasn't very appealing at all. It was either a case of restarting with fresh exposures or trying reprocessing with more modern tools and hope for the best. And here is the result. Not what I originally hoped for but still worth pushing out in the public eye.

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.
