NGC6751, the Glowing Eye Nebula, HOO & LRGB (AnaTa)

NGC6751, the Glowing Eye Nebula, HOO & LRGB

This is probably limit for my rig. Nebula is 20". I magnified it as much as I could.
Panel B show LRGB capture for whole field with this tiny nebula in corner.

Processing LRGB image:
RGB are combined.
Cropping for Lum and RGB
DBE for Lum and RGB
Color Colib for RGB
Blur and Noise XT for Lum and RGB
Manual stretching (with HT) for Lum and RGB
Made LRGB image
Noise XT again for LRGB
Stretching again with HT for LRGB
Important: star XT did not work. It wiped out half of tiny nebula.
Local Histogram Equalization: Kernel radius of 10 and then 40
Multiscale-median transform for sharpness, setting 0.4-0.5.
Curves: saturation and brightness are manipulated.
Done

Processing HOO image:
Massive cropping for O3 and Ha
DBE for O3 and Ha
Blur and Noise XT for O3 and Ha
Manual stretching (with HT) for O3 and Ha
HDR Multiscale Transform. Setting 5
Local Histogram Equalization: Kernel radius of 10 and then 40
Multiscale-median transform for sharpness, setting 0.4-0.5.
Combined with PixelMath using:
Red: 1.1*Ha-0.5*O3
Green: O3+0.4*Ha
Blue: 1.2*O3

Local Histogram Equalization: Kernel radius of 20
Multiscale-median transform for sharpness, setting 0.2.
Curves: saturation and brightness are manipulated.
Cropped again. Stars are HOO!
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.
