This is SH2-86, which is a faint emission nebula in the constellation Vulpecula, close to the Dumbell Nebula.

I took these subs while back, but just got round to finally processing it.  I have a full set of Oiii and Sii too, but got hardly any signal from either, so in the end I decided to go moody black &  white Ha

I don't normally do starless, except for fun, but thought this one was rather striking:

SH2-86 contains open star cluster NGC 6823 which is about 50 light-years across and lies about 6,000 light-years away. The center of the cluster formed about two million years ago and is dominated in brightness by a host of bright young blue stars. Outer parts of the cluster contain even younger stars.

 

Hope you enjoy !
