M51 during some moonlight

Shot M51 and learned I need to manage my subs and calibration frames on my thumb drives when taking shots over multiple nights. The background isn't as is good as I'd like it. But this is only 2 and a quarter-hour of integration time. Lost a lot of subs due to failed star alignment. I'm also having issues with STF in Pixinsight that confounded me for a couple of weeks until I realized that STF was boosting a bit too much. I'm going to go back to some previous shots and see if I can clean them up. Between some failed processing, bad weather, poor organization, and some long work hours it has been a rough month.

Description: Okay, second take of this one with lower saturation and fake color. I'm probably going to go back for yet another revision, 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.
