I'm not sure why I never got to M11 before now. It's a great open cluster and I'm glad I finally stopped neglecting it!

Processing:
RGB:
channel combination
ABE
SPCC
blurxtterminator
GHS (a few iterations being careful not to clip)
noiseXterminator
curves (contrast, very slight color boost)
unsharp mask (very mild sharpening)
dynamic crop

The stretch is the big challenge for something like this. I wanted to bring out the dark nebulae but not blow out the stars. The approach I settled on was a couple of small GHS stretches followed by a linear move to the left, then another GHS stretch. The GHS stretches made fairly heavy use of highlight protection. The GHS stretches used the RGB blend color mode but I had to keep that fairly conservative or else the bigger stars got colored rings around them from being overly saturated.

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.
