Here I framed the image around the emission nebula SH2-115 but was unprepared and surprised by the richness of objects that the wider FOV captured.  Not far from Deneb, the large blue SH2-115 is energised by the open star cluster Berkley-90.  Numerous emission nebula from Lynds' Catalogue of Bright Nebulae (LBN) are adjacent to SH2-115 across much of the northern section of the image.  Using the SHO Hubble palette format, here the nebulosity forms a rich golden-brown ribbon, which is exquisitely sculpted by the prevailing interstellar forces. 

South (right) of SH2-115 is SH2-112, a circular emission nebula thought to be energised by a blue double star BD + 45 3216 at the centre, with dark clouds and filaments contorted around the periphery.  Finally, just north-west of SH2-115 is the small but enigmatic SH2-116, AKA Abell 71.  This faint, blue disc was originally thought to be a planetary nebula, but this is now in doubt and awaits further research.

All-in-all there’s much to see in this busy image, which is an astrophotographer’s treasure trove of exciting objects.
