A few tips: geostationary satellites are best photographed at 500 to 2000mm focal length. If using the longer focal lengths (telescope), you'll have to point rather accurately at a certain satellite or group of satellites. At 2000mm or even more, you'll be able to record the motion of the satellites with fine-grained film. They're not perfectly still over one spot, but instead move in a figure-8 (analemma)over the course of a day.
