Total Lunar Eclipse December 21, 2010
Taken from Smyrna, Delaware. I used a Celestron C8 telescope at prime focus using a Celestron f/6.3 focal reducer. Canon 40D, 1.3 second exposure at ISO 400. Effective focal length, 1260mm.
Camera setting details: Mirror lockup enabled. Shutter release timer set to 12 seconds to allow vibrations from mirror lockup to die down. High ISO noise reduction set to auto. Telescope polar aligned to track as accurately as possible.
