Markarian's Chain 4 Panel Mosaic

This 4 Panel Mosaic is the result of a slightly over ambitious plan to complete a mosaic while camping three nights at a remote dark site in the Coconino National Forest. Each panel needed a bit more data. And high clouds ruined one panel despite my best efforts at local normalization and throwing out the worst frames. However, at least I proved to myself I could plan this ahead of time and get the mosaic frames acquired. Perhaps next time I won't be more ambitious than two panels so I have plenty of time to acquire frames and sort out the best ones if the weather changes.

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.
