Abell 39 (Jerry Yesavage)

Celestial hemisphere: Northern · Constellation: Hercules (Her) · Contains: PK047+42.1

Abell 39

Color obtained with Rob's formulae and procedures:

Add in O-III to Green and Blue:

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

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

You can do this by:

1. using (DNA)linear fit to normalize the signal strength of your OIII to the green channel,

2. then use pixelmath to scale the OIII to 72%,

3. then average the green and scaled OIII.

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

After this I added in the O-III also as a false L to provide the detail inside the sphere.

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.
