Description

G65.3+5.7 ("the little Cygnus Veils"-similar angular proportions), is a very faint Supernova remnant (SNR), rarely imaged target, localized in Cygnus. It is composed of several diffuse and filamentary structures, such as SH2-91, SH2-94 and SH2-96.

The whole structure is located at a distance of over 2500 light years and covers a field of more than 4° engulfed in an extremely dense star field. Positioned in the sky just north of Albireo in Cygnus

It shows significant signals in both Ha and OIII, albeit everything is embedded in the surrounding galactic nebulosities.

I have only seen complete images for this target by 2-3 more people.....
