Finally managed to collect some Oiii data for this very fine target.

Sh2-224 is a very faint supernova remnant in the constellation Auriga, southeast of Capella. We need a very long integration time to make it visible.
It consists of two very faint parts. Its unusually shaped shell structure has a radius of about 25 parsecs and interacts with a cavity of the interstellar medium at a temperature higher than the surrounding environment. This suggests that the rest of the supernova came into contact with the cavity in a southwesterly direction, first deforming and interacting with this structure, then expanding within it. X-ray examination determined the age of the structure to be between 13,000 and 24,000 years old.

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.
