These were taken on 22 November 2003 from my back garden with an SLR on an ordinary tripod, with a 300mm lens at f/5.6 and 400ASA film. The exposure was about 25 minutes. The stars are whizzing past, but several tiny dots appear stationary.

You can find where to look for a satellite if you know its longitude and your own coordinates. This is a trigonometry problem (what do you mean, you can't do maths?) but I've written a simple Javascript program to do the sums. Off the top of my head, I recall the Astra satellites used for TV programmes are at 19.2°E. (Check satellite TV magazines, or I got the coordinates for my house from the excellent web site Heavens Above.
