SNR G126.2+01.6 - It's Dim!

Supernova remnant SNR G126.2+01.6 is located in the constellation Cassiopeia not very far from other popular objects such as IC 63 - The Ghost of Cassiopeia. I am always looking for uncommon objects to investigate with my camera and saw that Goran Nilson (https://www.astrobin.com/mj605m/) had done a wonderful job on this with his dual RASA setup. There are only a handful of other images of SNR G126 on Astrobin (all of which are better than mine) for a very good reason - this object is faint, especially in OIII. If you do decide to go after this one, give yourself plenty of nights! Processing was really tough, especially trying to 'tease' out the oxygen. Fortunately, PixInsight and Photoshop make it possible. I thought the stars came out well so the only reduction I did was with BlurXTerminator.
