Sharpless 119

Sharpless 119 is a largish emission nebula in constellation Cygnus. There are not too many images of it around due the close proximity of eye catchers, North America and Pelican Nebulae. Sh2-119 locates just three degrees East from the NGC 7000, North America Nebula. A bright magnitude 5 star 68 Cygni, can be seen at very center of the image above. There are several dark globules at the Southern part of the nebula.
This image covers about three degrees of sky, that's six full Moons side by side.

Technical details:

Processing work flow:
Image acquisition, MaxiDL v5.07.
Stacked and calibrated in CCDStack2.
Deconvolution with a CCDStack2 Positive Constraint, 33 iterations.
Levels, curves and color combine in PS CS3.

Optics, Tokina AT-X 300mm camera lens at f2.8
Camera, QHY9 Guiding, SXV-AO @ 6,5Hz
Image Scale, 3,5 arcseconds/pixel
Exposures H-alpha 10x1200s, binned 1x1O-III 3x1200s, binned 3x3
S-II 3x1200s, binned 2x2
Total exposure time ~5h
