So U have 2 choices: replace the entire shutter assembly on the Canon for $400 or get a 5D system for $3000. The 5D requires a flash ($400) & normal lens ($310) but it would make those space station flyby's much easier. Don't think the 5D Mark II is valuable enough to justify $3500. The credit card won't reset until next week, so no Canon replacement for a long long long long, really long time.
Decided we had enough still photos from last year's shuttle/station flyby & photos like this R so rare that it justified making a movie. All 47 handheld photos were hand stabilized. The 200mm lens couldn't bring out any detail. The only novelty is the fact that U know what they R & U can see how low they R by the aspect ratio changes as they move across the sky. Next time, use a 180' wide angle lens.
Finally figured out a way to stack timelapse photos, so U get some UAV painting.
The UAV tries to draw CAT, a vertical heart, & a horizontal heart all an autopilot. Things definitely look better from nadir.
