Belt & Sword of Orion (135mm 5DII).jpg
Belt and Sword of Orion, with Barnard's Loopp. This is a stack of 5 x 8 minute exposures at f/2.8 and ISO 1000 (set too high by mistake!) with the Canon 5D MkII and Canon L-series 135mm lens. The originals were overexposed but processed up nicely. Skyglow from Orion's altitude at home in Alberta adds the brighter glow at bottom of frame.
