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.
NGC 7006 globular cluster in Delphinus, a globular 130,000 light years away, so tiny at this scale with the 130mm f/6 refractor. Taken with the Canon 7D for a stack of 4 x 8 minute exposures at ISO 800. Taken from SSSP 2012
