NGC 6910 open cluster, the Sadr region, RGB-Ha and LRGB

Powered byPixInsight

NGC 6910 open cluster, the Sadr region, RGB-Ha and LRGB

Image of the NGC6910 open cluster has SNR of 150

Processing:
Dynamic Crop for R, G, B, Lum and Ha
RGB combine.
DBE for RGB
Color calibration for RGB
Blur and Noise XT for RGB, Ha and Lum.
Star XT for RGB
Standard linear HT stretching for RGB (strong stretch) and RGB-stars (medium stretch)
Standard linear HT stretching for Ha and Lum

LRGB was created.
Noise XT and then HT stretch again
Curves for star and nebula saturation and brightness adjustment.
Annotation (panel A)

Noise XT on Ha and stretch again.
Star XT on Ha. Stars are discarded
LHE for Ha. Kernel radius 40 and 150 (setting 0.2-0.3)
Ha was added to RGB-stars using pixel math. This created RGB-Ha.
Curves for star and nebula saturation and brightness adjustment.
Done. RGB-Ha (panel B)

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.
