The rarely imaged SNR G126.2+01.6 in Cassiopeia

The first monochromatic images of this faint supernova remnant was published in 2005 (http://outters.fr/wp/wp-content/uploads/2020/12/Deep-optical-observations-of-the-supernova-remnants-G-126.2.pdf) and it was subsequently described as a radio source (https://www.aanda.org/articles/aa/pdf/2006/07/aa4036-05.pdf). There are apparently very few colour images of it. In fact I have only found one on Astrobin, which was posted about three weeks ago (https://www.astrobin.com/lzaexz/C/?q=SNR%20G126.2%2B01.6%20and%20surroundings%20%28first%20color%20image%29).

The little red dot near the top right corner is the almost equally rarely imaged Sharpless object Sh2-186. One reason for this is probably that it is so tiny, possibly the smallest object in the Sharpless Catalogue. Here is a super-crop of it:

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.
