One more suggestion: if you need a normal/wide field lens and "long"
exposure to capture a slow flasher, you could reduce exposure times
by holding a black cloth, or lens cap, in front of the camera
(not touching it) while the satellite is dim.

You may even want to do this on a steady satellite, to get an entry
track in one edge or corner of the picture, and an exit track near
the opposite edge.,Internet
