In astrophotography noone cares about sharpless pictures. However one of the astronomy catalogs is called Sharpless – it was published by the US astronomer Stewart Sharpless in 1959, and contains 312 objects that are HII regions (emission nebulae). 
The one at position 112 is not so popular region, but I decided to picture it over two extremely short June nights. This region is placed about 5700 light years away, and can be found in the Cygnus constellation nearby its brightest star – Deneb. Nebula itself has apparent diameter about 15′ and is immersed in much larger, but not so bright hydrogen cloud, that makes whole frame deep red.
