Messier 15, yet another globular cluster. I wish I'd taken the time to take exposures at two different lengths to see if I could combine them to resolve deeper into the core but, alas, I didn't plan ahead well enough.

There's a hint of some dust or perhaps IFN on the right side of the frame. I think it's real though I couldn't bring it out more without harming the rest of the image.

Somehow the red got away from me here and I ended up with far more than I intended.

After all the recent narrowband imaging this is pretty straightforward processing:

R, G and B masters:
dynamic crop
DBE

L:
dynamic crop
deconvolution
DBE
histogram transformation

RGB:
channel combination (RGB)
PCC
histogram transformation
LRGB Combination

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.
