The pair of large open clusters, NGC 6633 at right in Ophiuchus and IC 4756 at left in Serpens, in a wide-field image simulating the field of binoculars. Taken July 24, 2012, from home with the Canon 5D MkII at ISO 800 and Canon L-series 200mm lens at f/3.5 for a stack of 5 x 3 minute exposures. Also known as the S-O Double Cluster.
NGC 7000 and nearby Pelican Nebula IC 5067 with TMB 92mm apo refractor and Borg 0.85x field flattener for f/4.6, with Canon 5D MkII (Hutech modified) at ISO 400 for stack of 4 exposures x 8 minutes each. Guided with Solitaire autoguider as a test. Sky not dark yet (moonlight) in first couple of exposures.
NGC 7000 and Pelican Nebula with TMB 92mm apo and Canon 5D Mk II on a superb night, with stack of 2 x 15 minutes + 2 x 12 minutes at ISO400 and Borg 0.85x flattener/reducer for f/4.6. Standard exposure is 12 minutes but the night was so good I did two at 15 minutes with no problem.
