    You probably want the highest ASA settign possible - ISO 3200.  Also the widest 
    F/stop possible.  Shutter speed should probably be short for fast moving 
    satellites - maybe 2-10 seconds.  For slow moving satellites you can go up to 15 
    seconds unguided.  Longer than that and the stars will trail too much.  For 
    guided shots I prefer multiple 30 second exposures stacked using software suck 
    as registax or other better programs (that aren't free).
