M51 (The Whirlpool Galaxy) with some very faint fuzzy friends

From the UK M51 is at its maximum altitude during May which unfortunately is the time of year when nights shorten leading to complete loss of astronomical darkness during June. Fortunately we had some fine nights during early May and I was able to acquire sufficient data over two nights to compile this (I hope) reasonably decent image. A little more luminance data would be nice to allow me perhaps to bring out a little more of the luminosity around NGC5195.

Description: This was one of my earliest attempts at AP. I was very pleased with the image at the time but, now three years on, I see numerous issues. Decided to reprocess and to include some additional, recently acquired data. I feel this latest version is a marked improvement.

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.
