Equipment Details:

Pentax digital camera, Sigma 50-500 lens

Post-processing Details:

I got shots of the eclipse at 11:00, 12:12, and 1:22 EDT. Half covered, mid-eclipse, and half uncovered.
I composited them onto an official trajectory to show how the moon "reveals" the shadow of the earth in space. Since the moon is at perigee (closest) this time, the shadow seems larger and the eclipse lasted longer (the moon takes longer to "traverse" it.) When the moon is at apogee, the shadow "cone" of the earth is smaller (at that distance), and takes less time to pass thru. My composite adds stars (the moon is so bright, the actual photos don't show stars), with them artificially dimmed to help depict the shadow.
