Sh2-114 (the Flying Dragon Nebula) is a very faint and rarely imaged nebula located in the constellation of Cygnus. The nebula has not been studied much and still doesn't seem to be a common target for astrophotography. This large curving filamentary structure appears part of a supernova, but no supernova remnant has yet been identified as the source.

After about 13.5hs and four sessions, the weather turned, so I have to be content with the data for now. Processing was challenging and I believe another 10hs or so would be beneficial. It was fun making the dragon appear.
