M9 globular cluster, LRGB

M9 a bright (7.7 Mag) and medium-sized (9') globular clusters in the constellation of Ophiuchus. It is one of the nearer globular clusters to the center of the galaxy center; it is around 5,500 light-years from the Galactic Center.  SNR of cluster is 10.

Processing:
WBPP was used to calibrate, normalize and integrate Lights using for calibration Darks, Flats and Dark Flats.
R, G, B and Lum were slightly cropped.
GraExpert applied for R, G, B and Lum. GraExpert produced noticeable effect, since image captured at bortle 8.
RGB were combined.
SCPP was used for color calibration.
Blur and Noise XT for RGB and Lum.
Stretching required gradual application of wider and wider masks generated in GAME script.
Manual stretching for RGB and Lum were done using HT.
Noise XT, and then stretch again.
Mask with Lum.
LHE was applied: 40 and 150 Kernes radius (setting 0.2).
Then MMT was applied for sharpening (setting 0.02-0.03).
Curve was used for star saturation adjustments.
Blue and Yellow masks were used to enhance blue.
Mask with Lum for overall star saturation.
Annotation is the panel C

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.
