Telescope/Mount: Celestron Super C8 Plus/Byers drive mount.with Celestron f/6.3 focal reducer-corrector.
Camera: Canon EOS 20D
Location: Portland, OR, USA.
Exposures: Stack of eight 2-second exposures, total exposure=16 seconds.
In Portland, Oregon, the moon rose just before onset of totality and climbed only a few degrees above the horizon before totality ended. Therefore, I had to shoot through a great deal of atmosphere, under a fairly bright twilight sky. To make matters photographically more difficult, it was a very dark (L=2) eclipse and conditions were windy. Long exposures were blurred by wind shaking the telescope. For this image, I stacked eight 2-second exposures, which gave me a much better signal to noise ratio than in the stack of only four 2-second exposure I posted earlier.
