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 four 2-second exposures.
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. Accordingly, for this image, I stacked four 2-second exposures. I processed the image to even out the incredible dynamic range of this dark eclipse to show color and detail in both the very bright and very dark regions of the moon within the umbra.
