Cirrus of Cygnus and the supernova remnant W63
The dim are in the Western Cygnus is very much overlooked, the reason must be the there are so many brighter and well known astronomical objects just nearby.
Hydrogen filaments in the image are about thousand light years long, the blue ring in the image is a rarely seen dim and large supernova remnant, the ring structure is seen only in light of an ionized oxygen (O-III)
I haven't seen any photos focusing to this area beside my older shots of it. This new composition is reprocessed and more data is added, specially in O-III channel. This image is a part of new unpublished mosaic image, it'll cover the whole Cygnus complex.
Image is shot with several instruments between 2010 and 2020, Original frames from 2010-2013 are shot with canon EF 200mm f1.8 camera lens and QHY9 astro camera with Baader narrowband filter set. Additional wilde filed frames are shot with Tokina AT-x 300mm f2.8 camera lens and Apogee Alta U16 astro camera and Astrodon narrowband filters. Many details in the image are sot with Celestron Edge 11" telescope and an old Meade LX 200 GPS 12". total exposure time is around 150 hours. I gave the name "Cirrus of Cygnus" since this gas formation remains me about Cirrus clouds.
Cirrus of Cygnus
You should click the image to see it in full resolution, it's worth it! (3000 x 1250 pixels)
A mapped color image from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen. Note, there is a size of the moon marked in lower left corner as a scale.

It does look like a Cirrus cloud

Image is in mapped colours, from the emission of ionized elements, R=Sulphur, G=Hydrogen and B=Oxygen. This mosaic image of twelve individual panels covers about four degrees of sky vertically.
