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.
Stack of two 6 minute exposures at ISO 400 and f/4 with 15mm lens and Canon 5DMkII camera. Taken Sept 10, 2009 with Moon just rising or about to, so sky is brighter than normal.
