Hydrogen Alpha, Nitrogen II, and Oxygen III filiments from Super Nova G082.2+05.3 David Green's Catalog.
This is processed to highlight shockwaves from SNR's.
I count 5 nearly complete shock spheres from SNR's in this image.
Included is the subject of the image, a nearly spherical OIII shell for SNR G082.2+05.3 previously reported as spectral signatures and a "Radio Shell in the Cygnus X Complex". The OIII filaments size closely matches the radio signature of 95X65 minutes and is in the correct location. It is the bluish circle near the center of the image and is about 1/3 the horizontal image axis in diameter.
The image is about 240h X 360v minutes of arc in size.
