1000antares

The Antares region by a Canon 1Ds. North is roughly towards the left. Stack of nineteen 2.5 minute frames at f2.8. 100mm lens autofocused on Alpha Centauri then turned to the target. Dark-subtracted and flat-fielded. Frankly this region is quite dim and I would have appreciated having 4 times as many frames to stack. The stars are bright enough, it's that colorful nebulosity that's so difficult to coax out. Next time...

Canon EOS 1Ds ,Canon 100/2.8macro USM

other sizes: small medium large original
