M101 with supernova May 20th 2023

I took this image as one of a set of M101 during a few clear nights between May 16th and May 24th, following a couple of months of cloud. I wasn't aware of the supernova SN 2023ixf at the time, it was just pure luck that I caught this image a day after discovery.

This isn't the best image as it is only one night of data and the summer nights are fairly short in the UK, but I wanted to post the image for one night with the supernova shortly after discovery. I will create a deeper stack of several nights as a separate image.

I used PI drizzle integration with a scale of 2 and drop shrink of 0.75

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.
