Date: 9 February 2008
Location: Dungeness, Kent
Exposure: 5 x 5min at ISO 800
Telescope: Celestron C11 on Skywatcher EQ6 mount.
Camera: Canon EOS 300D + 50mm lens at F1.8
Processing: Stacked in IRIS and asinh range compression applied.
Comments: The camera was piggybacked on an unguided scope.
Unfortunately, at F1.8, the lens shows significant aberrations towards the corners giving very misshapen stars!
The Orion, Horsehead and Flame nebulae are quite visible and there is just a hint of Barnard's Loop over to the left.
