    I thought I have some fun, and use ted's program to measure a position for Aqua. 
    
    I captured a still image from a pass of of Aqua.
    
    http://www.kfetter.100megs26.com/observe/aqua.jpg
    
    The time of the still is May 5, 2005 at 6:33:05.9602 UTC +/- 0.03 seconds. 
    
    The config file I used.
    
    http://www.kfetter.100megs26.com/observe/ObsReduce.ini
    
    Aqua is 27424
    
    I measured the screen and got 15 mm / 62 mm. 62 mm is what I got for the distance between the
    bright star at the top, and the bright star at the bottom, that aqua form's a line with. Aqua was
    15 mm from the bottom bright star.
    
    So 15/62= 0.2419 So I used 0.2419 where it say's frac AS/AB
    
    I would estimate aqua was around mag 4.9 at the time.
    
    I got the following result.
