    Re: Scope position relative to frame 2
    From: Bill B

    Sorry to be thick as a brick on this.  I did find an article Frank had
    posted, "Sextant Telescope Collimation," 10-18-05
    I guess my handicap is not being able to translate the word picture into a
    mental image.
    If I superimpose two images in the center of the scope and keep the
    directly-viewed image centered and rotate around scope's axis, the image
    viewed via the index mirror will slide left or right using a plumb sextant
    frame as a reference.
    What I suspect is a movement more like assembling a panoramic from several
    camera photographs.  If the scope had cross hairs, when the sextant frame
    was in the normal plumb position, we could label the horizontal cross hair
    "x" and the vertical crosshair "y".  With the two images superimposed at the
    crosshair junction, the "rotation" motion needed would slide the bodies to
    either side of the y crosshair while keeping them on the x crosshair.  Equal
    distance from the y crosshair of the image nearest the y crosshair should
    create equal separation between the bodies.
    Do I have it yet?
    Thanks for your patience.
