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.

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.
Deneb and North America Nebula area, taken September 4, 2007 from home. Stack of 5 x 4 minute exposures at ISO800 with Canon 20Da and 135mm L-lens at f/2.8. Field equals 7° bino field. Sharper focus than Aug 15 attempt. Two of the images were taken later after refocusing and reframing and were far off register but CS3 "Align Layers" registered them precisely.
