This faint supernova remnant requires a lot of imaging time. I gathered almost 30 hours of useable data over many nights during Dec '23 and Feb '24. Some nights had small clouds rolling in and out so I shortened my exposure times during those evenings because the clouds would present themselves often enough to ruin my ten-minute exposures. As a result, quite a few frames got rejected; otherwise I would have had over 30 hours. I'm generally pleased with what I was able to capture, but it definitely had its challenges. I also wasn't aware of PK 116 + 00.1, that u-shaped bright spot in the image. I initially thought it was a weird artifact on my ha filter. Upon further investigation I learned it was once thought to be a distant planetary nebula, but it’s more likely to be a region of ionized hydrogen (HII), which I believe, because it’s only present in my ha images and doesn’t show up at all in my oiii master image which has 13 hours of integration.

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.
