Orion region taken with this mount ( http://www.pbase.com/emagowan/image/159208699 ) 19 February 2015. Big Lagoon State Park, Florida.
About 30 minutes total exposure, modified Canon 40D and EF 50mm/f/1.8 lens @ f/2.2.
Stopping down to f/3.5 or f/4 would have eliminated the coma in the corners, but
there was only time for this sequence, Orion was headed for a light pollution dome.
Horsehead, Flame Nebula, M42, Running Man and Barnard's Loop.
