 ISS reached 77 degrees altitude in SW
 ISS departed to SE
 This ISS pass was above the trees for only 80 seconds
 
 Mount:

 Firecapture v2.4.10 captured ISS as an avi movie
 Gain = 499
 Shutter speed = 1.4ms
 Lossless 'Ut Video' codex
 
 Procedure:
 
 Set Laptop and 900GTO mount clock to within 1 second.
 Focused and ReCal on Capella
 
 Used Step and seconds buttons in Satellite Tracker to find the ISS
 After ISS was on sensor, switched from buttons to Joystick control
 An accurate polar alignment will result in less joystick corrections.
 
 Post Processing:
 
 Used Virtualdub to remove blank frames and set final playback fps
 Used Pipp to debayer GB to RGB
 Used Pipp to center ISS
 Registax 5 seemed to refine centering.
