The Helix Nebula

Revision title: Blue Rays of OIII

I really wanted to highlight the rayed structure in the OIII channel here, and I was clearly able to capture it in that channel, but had to make a compromise between lots of interesting structure. I've seen others do better, so I may come back for another revision later.

RGB Stars, Ha -> 52°, OIII -> 244°, SII -> 0°

Title: OIII in grayscale

Description: The ray structure is very apparent in the OIII channel, but it's hard to bring it out in a color version without overwhelming the image.

Title: Blue Rays of OIII

Description: I always wanted to bring out more of the rayed structure, but didn't want to lose the Ha/SII signal. I've recently started experimenting with Topaz Denoise, so it seemed like a good opportunity to do a new and improved blue version of the helix.

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.
