M81 and M82 on an Alt/Az Mount

A reprocess of one of my earliest DSO imaging attempts. I never posted the original because most of the galactic arm structure was lost in post. However, since I have learned better use of Star Tools I have improved my efforts on post.

Removing the Vignetting from the frame edges was especially difficult, as since I was using an alt/az mount, the object (especially M82, being near the edge) was slowly rotated through the hour or two I was pointed towards it. This caused the light pollution gradient to be in very different places from the first exposure to the last. I was able to remove most of it with a brush in Lightroom following Star Tools, but some still remains. I look forward to imaging this object again in several months when it starts rising in the NE.

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.
