This result won't please astrophotographers with advanced equipment or pixel peeping connoisseurs. Nevertheless, I'm happy with the result from using a limited number of subs captured by a smart telescope. If I can amass more quality subs and get better at processing globular clusters, I think the result will improve.

Editing this Stellina fits stack was by trial and error. The subs were of poor quality - I think humidity and the target's location above horizon were factors. Of the 1,287 lights collected 2023-06-14-15, I stacked 180 in Astro Pixel Processor (with 200 darks.) It would have been 134 lights if I'd used only subs with a quality and star shape >0.7. I prefer 0.8. I may try stacking the 123 since there's no nebulosity. I hope to get more images when the humidity is lower to eliminate that variable. I may try two Stellina Plan My Night sessions, one for when M13 is rising and below 80° above horizon and another for when M13 returns below 80°.I tried editing Stellina's tiff file in PixInsight first, but I couldn't address some of the issues. The APP stack was easier to work with, but I needed to use both PixInsight and Photoshop to edit.

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.
