M105-NGC3384-NGC3389, LRGB

Image of a group of galaxies including M105 with Edge SCT9.25 has about SNR of only 3.
Two panels are LRGB (Panel A) and LRGB annotation (Panel B)

Processing:
Dynamic Crop for R, G, B, Lum
GraXpert for Lum, R, G and B.
RGB combine.
DBE for RGB
Color calibration for RGB
Blur and Noise XT for RGB, and Lum.
Star XT for RGB. It is again not perfect for some elliptical galaxies; and "extract" off some part of galaxies, including M105.
Standard linear HT stretching for RGB, Lum and RGB-stars

Panels A and C:
LRGB is created.
Noise XT and then HT stretch again.
Star XT
Mask with Lum.
LHE, Kernel radius 40 and 150, power 0.2
MMT sharp
Curve for saturation and brightness adjustment for galaxy.
Curves for Hue adjustment
Curve for star saturation of RGB stars.
Added RGB stars to Galaxy.
Annotation (Panel B)
Cropping (Panel A)
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.
