Abell 61 RGB O-III H-Alpha (Jerry Yesavage)

Celestial hemisphere: Northern · Constellation: Cygnus (Cyg) · Contains: PK077+14.1

Abell 61 RGB O-III H-Alpha

Complicated processing of this object.

Started with the RGB image and added in the O-III to both B and G channels via Rob's (Pfile's Formula):

"In the RGB color model #00b8e0 is comprised of 0% red, 72.16% green and 87.84% blue."

This produced Image A.

I researched the actual color of H-Alpha at 656.3nm and as far as I can tell it is pure Red. There is a big H-Alpha signal here (Image B).

I then used my Sharpless2 techniques to add in the cleaned stretched H-Alpha into the R channel of the RGB images (that already had the O-III Teal). (Final Image)

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.
