Revision title: Cropped and post-processed with Astrosharp AI deconvolution after star removal with StarNet++

Because dew had gotten inside my Stellarvue 140 triplet lens, I had to remove it and give everything a good cleaning. This is the first imaging run since then. Smoke from Canadian wildfires continues to degrade transparency. There was a waxing gibbous moon wising and I am in Bortle 6 skies. Seeing was better than average for my area, probably just under 2 arc sec. I took 5 hours worth of 2 min subs but had to discard the last hour because of declining transparency and heavy dew formation again in the wee hours of the morning. This is an uncropped image of the original stack. Photometric color calibration against Simbad and Lucy-Richardson deconvolution were the main post-processing steps. I used Topaz Labs De-Noise to smooth the background a bit. Usually I avoid doing this, but here it seemed to help.

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.
