    Astigmatism
    From: Bill B
    Date: 2007 Jan 03, 18:26 -0500

    Texts and list members suggest the scope focus mechanism can be adjusted for
    near- or far-sighted problems, but some form of vision correction if called
    for with an astigmatism.
    
    If the distortion is not corrected with eyeglasses or contacts, how will
    this affect natural horizon observations, lunars or IE checks?
    
    Thanks
    
    Bill
