Gamma Cygni nebulosity aka the IC 1318 complex, plus the Crescent Nebula, NGC 6888 at right, in central Cygnus, taken on a superb night from home July 30, 2011. This is a stack of 5 x 12 minute exposures at ISO 800 with the filter-modified Canon 5D MkII and the Borg 77mm f/4.3 astrograph lens (300mm focal length), and using the IDAS V3 nebula filter. Orientation is tilted off true north at top (my usual orientation) to take in NGC 6888 and the little blue reflection nebulas at upper left.
Nebulosity in Cygnus, with 135mm telephoto lens at f/2.8 and Canon 5DMkII at ISO 400, for stack of 4 x 7 minutes + 4 x 4 minites at ISO640 for "glow layer" with Kenko Softon A filter. Some trailing from inacurrate polar alignment.
Gamma Cygni area, NGC 1318 and NGC 1311, with 135mm Canon L-lens at f/2.8 and Canon 20Da camera at ISO 800 for stack of 4 x 4 minute exposure. Taken Sept. 8, 2007 from home. M29 and NGC 6910 clusters in field. Sharper focus than Aug 15 version.
