I could not combine Lum with RGB, since gamma-Cas was too bright and hallow was big and "spilling" on nebula.

Processing:
R, G, B and Ha cropped.
GraXpert cleaned background.
RGB combined.
DBE for RGB
Color calibration for RGB
Blur and Noise XT for RGB and Ha.
Star XT for RGB. These stars were used later.
Star XT for Ha

HT was separately applied for Ha (no stars), RGB, and RGB-stars.
Create RGBHa
Noise XT, stretch again RGBHa nebula.
Mask whole nebula.
LHR with Kernel radius 40, 150 and 300
MMT sharp was applied.
Curve for saturation and brightness adjustment

RGB stars were masked and blue masked and clone stamped to clean gamma-Cas hallow. Horrible hallow!
Saturated stars were added to final image.
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.
