A Dying Star's Magnetic Racing Stripes (NGC 6894)

This title is from Phil Plait who has an excellent description for what may be happening here...

And an excellent science paper...

Skies were very dark and steady during this data acquisition with the FWHM on the 10-min Ha subs between 1.26" and 2.2". OIII subs varied between 1.3" and 2.2".

Nearly all the "racing stripe" energy is in Ha with the majority of OIII in the core perimeter.

A light RGB screen was placed over the top to add a bit more star color. The HaOIII combination was tuned to have nearly the same color balance as the RGB for both the stars and the nebula core.

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.
