Description

This objects captures many objects - Ha emission nebulae, a dark nebula, and a supernova remnant - in the constellation of Cygnus at a declination of +46 degrees. Cygnus is my favorite constellation in the sky for imaging, with many uncommon gems like the ones in this image.

The supernova remnant is easiest to see because it is the only OIII (cyan) object and it is in the foreground. This is SNR G082.2+5.3, believed to be about 5,000 light years away. The width of the remnant in this image is almost 100 light years.

The Ha emission nebulae are numerous, including LBN 313, 325, 326, and many DWB objects. These are likely behind the SNR and unrelated to it. I could not find any distance estimates for these Ha nebulae.

The dark nebula designated as Barnard 345 is in the top left of the image but is very faint.
