SNR G156.2+5.7 - A faint supernova in Auriga

SNR G156.2+5.7 is a very beautiful supernova remnant in the constellation Auriga, around 5000 light years away. It is situated behind the Taurus Auriga dust complex about 300 light years away, which gives it the ghostly appearance of weaving around dark nebula in the foreground.

This supernova has been very neglected in astrophotography, I could only find three other examples of it being captured, one from the UK, one from Japan, and nicolas outters. Only the image on the Japanese forum showed it in full color. The many papers on this object do also show very nice deep wide Ha images of the remnant, so there was a gurantee that something cool was here.

This SNR is very very faint, and I tried to shoot more Oiii than Ha to try and pick up something more, but this SNR is really lacking much Oiii outside its core. If you're going to go for it, I would do a lot more Ha.

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.
