M81, the Bode's Galaxy, LRGB-Ha

Image of the Bode's Galaxy M81 has SNR of 30.
Two panels are LRGB-Ha (Panel A) and LRGB-Ha annotation (Panel B)

Processing:
Dynamic Crop for R, G, B, Lum, Ha
GraXpert for Ha, Lum, R, G and B.
RGB combine.
Additional DBE for RGB
Color calibration for RGB.
Blur and Noise XT for RGB, Lum and Ha.
Star XT for RGB, Lum and Ha. This step is important, since Star XT on the other steps will remove small Ha-regions in the galaxy.
Standard linear HT stretching for RGB, Lum, Ha and RGB-stars.

LRGB (no stars) was created.
Ha region was blended to LRGB using PixelMath.
Noise XT and then HT stretch was again applied.
Mask with Lum.
LHE, Kernel radius 40 and 150, power 0.3
MMT sharp
Curve for saturation, hue and brightness adjustment for galaxy.
Curve for star saturation of RGB stars.
Added RGB stars to the Galaxy (Panel A).
Annotation (Panel B)
Done.

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.
