Lynds Bright Nebula 216 (DWB 28) is a is a fairly bright nebula located above the Sadr region in Cygnus. Various dark nebulae including LDN 871, 875 and 876 surround it. The field also includes DWB 29, 31 and 35. The catalog of various Ha regions located in the Cygnus X Region was published in 1969. The paper with catalog can be found here - http://adsabs.harvard.edu/full/1969A%26A.....1..270D.
Lastly, there’s an odd planetary nebula at the bottom left. PN G075.6+04.3 appears to be bright in Ha which is unusual. I also found it bright in some OIII exposures I took. See the annotated version for the locations of the PN and the other objects above.
Ha – 25x1800s – 750 minutes – binned 1x1
RGB – 8x300s – 40 minutes each – binned 2x2
870 minutes total exposure – 14 hours 30 minutes
