This is an early attempt at the Messier and assorted galaxy field in Coma Berenices with the William Optics ZenithStar 61 II APO. I was initially running a rough framing shot as I was trying to hop around to Markarian's Chain, when M99 and M100 popped up in the short test exposure with their gorgeous spiral structure. So I changed modes and opted for that field instead. I was hoping to start off with a bit more than 2 hours of exposures, but clouds became a problem and I could only use 76 minutes worth. I have not yet tried integrating multiple sessions, especially reframing the view to be as close as possible to previous runs (using iOptron SkyGuider Pro, so no automation to reacquire). Anyway, that will be fun later, because I definitely want to add more time to this one.

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.
