Ursa Major

Revision title: Cropped and re-processed

Hunting for targets near the zenith, and the only really clear sky, had me in Ursa major, wondering what this famous pair of galaxies would look like in a wide field. In the end not too shabby, but 2.5 hours under a bright moon was never going to be amazing. Nothing new here, for the original I pre-processed 60s and 180s frames together (a no no) for the revision (final), I pre-processed the stacks separately, and a bit more gentle on the processing - you can just about see the blue star clouds in M81 and a hint of the starburst core in M82 🤔 No sign of the ISM though 🙄

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.
