    Side error etc (Re: Beginner)

    errors out, and check for  side error with a star or horizon, but little
    more."
    
    The mathematical  details are discussed in Chauvenet's "Manual of Spherical
    and Practical  Astronomy". This important two-volume treatise is now available
    online at
    http://www.hti.umich.edu/m/moa/ (many other important titles here, too). If
    you don't like the math yourself, I'm sure one of the mathier list members
    would  be happy to quantify the errors that result from lack of mirror
    perpendicularity  etc.
