Here is a rather busy part of Cygnus captured in a two panel mosaic over two nights, mainly shot under a full moon with the RASA 8 and ASI2600MC equipped with the IDAS NBX dualband (Ha+Oiii) filter. The bluish structure is a very rarely imaged and extremely faint gigantic Super Nova Remnant (SNR) without a name but at least with a designation: SNR G 082.2+0.53. From my FOV I can calculate that the SNR must have an angular diameter of 1.3°, which is nearly three times that of the moon (0.5°). The right panel contains 4.2 hours of data (50 x 5 min) and also includes LBN331 on the top. The left panel contains 2.3 hours of data (28 x 5 min) and includes three nebulae from the Sharpless catalogue: Sh2-112 (down in the left corner), Sh2-115 (unfortunately a bit cut off on the left edge), and Sh2-116, which is the red dot above Sh2-115. It may be a planetary nebula.
I had never heard of this SNR before and I had no idea that it was in there when I first aimed at the area last week. I have the feeling that it is even fainter than the Squid and I am not sure if there are any other images of it except on this site:

Later on Thursday night, when Cygnus fell below my obsy wall, I aimed at IC405 & 410 and it was clear that the subs became more cotrasty after a few hours when the moon fell below the forest here.
