Here is a large field including this super nova remnant in narrowband with H-alpha as red, Oxygen III as cyan, and Sulfur II as yellow. There is a lot of sulfur in this object.
SNR G116.9_00.1, LBN 576, Abell 85, CTB 1, Popped Balloon, Garlic, or Medulla Nebula. And I picked up a couple more Sharpless objects Sh2-168 and Sh2-169 to make this a worthwhile effort for me ;-}.
The super nova remnant is 10,000 ly distant and also 10,000 years old.

18 x H-alpha, 20 x Oxygen III, 18 x Sulphur II
Color mapping: Hydrogen alpha red, Oxygen III cyan, Sulphur II yellow.

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.
