M13 Globular Cluster in Hercules (2023)

Revision title: 2024 Reprocess

It's been a while since I last imaged M13, and I wanted to give it a go with my CEM26 guiding on both axis, sticking to short exposures. I added six hours to 2021's two, and I feel like the effort was worth it - now I just need to go back and get more time on M5 & M3!

This was really fun to process, as the resulting stack had a fair number of stars. I found it particularly beneficial to use a circular gradient mask to prevent any noise reduction to the globular itself, as the fainter stars are exactly the sort of noise pattern that would be removed. This preserved all of those fainter stars, and I was able to keep them in the data through the rest of the processing.

I'm happy with the result, and excited to share it. CS to you all!

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.
