Abell 6 O-III H-Alpha RGB (neighbor to HFG 1) (Jerry Yesavage)

Abell 6 O-III H-Alpha RGB (neighbor to HFG 1)

Hi.

This started as another in the Abell series but I saw this artifact in the upper left corner of my O-III and did some looking around. Turns out this is HFG 1, which is visualized is an excellent image by Gary:

I decided to just put up the O-III as planned with the O-III wide angle to show the relationship and also the strength of the O-III (strong).

As another project I would like to reproduce Gary's image with a lot of H-alpha and O-III using his coordinates.

Description: Normal O-III colored image using Rob's tricks:

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

Usually blended in my OIII data to my green channel data at 72% strength and at 88% strength into blue.

you can do this by using (DNA)linear fit (execute script) to normalize the signal strength of your OIII (target) to the green channel
then use pixelmath to scale the OIII to 72%,
then average the green and scaled OIII.

repeat for blue channel on a fresh copy of the OIII.

Description: To carry this another step further, here is the recentered H-alpha with both objects included. This is 8x1800s with noise removed by Topaz AI.

Now to register with the other Abell 6 images then update the Abell 6 to include the HA?

I am going to recollect the O-III to include both objects and make a separate big final image.

Description: HA added to Red channel as I do normally for HA but no big changes... the signal is weaker than the O-III... maybe the "crust" is sharper. I will get a few more HA for the overall image and see what that does.

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.
