For tonight's ISS pass, I set up the 10-inch and added a 2.5x Barlow with the 
digital video camera.  In order to prevent motion blur, the camera has to 
record at 1/2000 second or faster.  This resulted in very faint images on the 
chip at f/15, even though the ISS was as bright as Venus.  Out of the 7791 
frames taken in just over two minutes, five were good enough to put into this 
time-lapse animated GIF.
