Another project from the New Horizon led by @Tim Schaeffer and editor @William Ostling.

SNR G126.2+01.6 was partially imaged by Nicolas Outters in 2020: SNR G126.2+01.6 – Outter'space Astrophotography (outters.fr)

We took on this region to image this low surface brightness SNR and its surrounding regions. Imaging was done in my backyard, which is slowly becoming light polluted. In the course of imaging, I ran into halos with the O3 filter, and I had to get Chroma replace it with their F/3 version once I explained my imaging train.

Presented in Final is Will's edit and mine as a revision.

The OIII emission as shown in radio and spectral index study:

Will's edits and my edits

Few other regions of interest:

Open cluster NGC609

Open cluster NGC559

PK126+03.1

SH2-186
SH 2-186 is ionized by the B0 III giant Hiltner 102 and is part of the Cas OB7 association.

Conclusion:
Overall, this was a fun region/project to image and collaborate. I'm looking forward to imaging interesting regions up in the night sky!

Hope you like this result. Clear skies!

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.
