M101, Supernova SN 2023ixf, compared to M101 April 2021

The top photo was shot April 2021, from dark skies in Escalante, UT, when my astrophotography skills were even more rudimentary than now, with a Celestron C8 and a Nikon D750. Early in the hobby, I hadn't yet developed a system to record details on exposure length, # frames, etc. so I don't have acquisition details on the top image. Notably absent is the bright white-blue ball noted in the photo below, taken on the night of 5/21, with better equipment and a few more skills, though through hazy, light polluted skies. Had to throw out much of the data I otherwise could've gotten because of clouds. The acquisition details here noted are for the bottom photo from this past Sunday night. Clouds this week are preventing further observations. Many on here have much better images of this same target, and I enjoy all the variety of renditions.

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.
