    Hi Ted and Tony,
    Thanks a lot for your interesting answers.
    I was looking to build something very accurate. I've been a tool, mold and die 
    maker for 13 years before being a teacher and I still have access to all kinds 
    of machine-tools. I got information about Heidenhain high precision rotary 
    encoder and PC interface cards. They make encoders for professional 
    observatories. I was to make a permanent setup in my backyard with a concrete 
    base resting on the underground bedrock (about 6 feet deep here).
    The advantage of Az-El coordinates is that once adjusted, if the mount is 
    steady, it doesn't have to be synchronized to the stars like the equatorial 
    coordinates. I wouldn't need reference stars, so measurements in twilight would 
    be easier as long as the satellite is visible.
    This is a long term project because I don't have much time these days. But I 
    really intend to do it and wanted your advice before going too far.
    Thanks again.
