resolution: 2048 x 1072 (600D 5x-crop)
frames: 686

aperture: f11 (10´´/2800mm)
frames containing nothing than space: 670
frames containing the ISS: 17
frames good enough for postprocessing: 5
For to know, at what time the ISS can be seen, I´m looking here:
www.astronomie.info/calsky/Satellites/index.html/4?interval=7And for to get a bit orientation of the fligh curve, I´m looking in stellarium (www. stellarium.org)
The clamps of the teleskop mount are loosen to be able to track the satellit manualy. And the broomstick helps to do this tracking more sensitive. The viewfinder must be aligned very accurate to the teleskop.
When I see the satellit appearing on the horizont, I must hurry up: Pointing to the satellit and trying to track it, using the viewfinder. When the ISS is quite high in the sky, I start the record. Two minutes later, the game is over. The bigger the resolution, the better the chance for catching the satellit. So, the 600D is not so bad for doing this
