Veil Nebula and NGC 6940, with 135mm Canon L-lens at f/2.8 and Canon 20Da camera at ISO 800 for stack of 3 x 4 minute exposures. Taken Sept. 6, 2007, on hazy night.
Stack of two 6-minute exposures with Canon 20Da camera at ISO400 and Astro-Physics 4-inch apo refractor at f/4.5. Second layer median filtered and gaussian blurred to add glows around brighter stars, and mixed in with Lighten mode at 100%, and contrast boosted by +50 to brighten stars.
Veil Nebula (both halves), with 77m Borg apo refractor at f/4, and Canon 20Da camera at ISO400, for stack of 3 x 14 minute exposures. Taken on a superb night, Sept. 11, 2007. Obscured area to the right is interstellar dust darkening the field and obscuring stars, not a defect. Guided with Meade DSI thru 66mm guidescope and PHD Guide software on Mac. Each frame precisely in register.
