A rim in Cygnus near Sadr (H-Alpha, H-Beta and OIII)

Found this while browsing through Stellarium, so payed it a visit. Think it looks interesting with those bright fog like clouds streaming from a rim. Also the almost cut off from a lot of stars on the left and way fewer on the right.
For those interested, the center of this capture is RA 20h19m04s / DEC +039°29'37" (J2000.0). In the lower right corner is dark nebula LDN 881, in the upper right quarter is LDN 882.

The Netherlands, Bortle 7/8

Ioptron CEM25EC mount (no guiding)
