The Great Orion
Nebula, as photographed on the evening of Febuary 10, 2012 from Mt.
Arizona at 9100 feet elevation. The camera used was a recently
modified Canon EOS 20D with a
new wider IR filter by Spencer's Camera & Photo in Alpine,
UT. A Canon f/2.8 400mm telephoto
lens was used at f/4, ISO 1600 for this 3 minute exposure.
With the 20D, the equivalent focal
length was 640mm, and tracked with a Losmandy G-8 mounting.
On the far right is the trail of
a satellite in a geosynchronous orbit.
