    Off Center Sextant Scope Observations
    From: Greg Rudzinski
    Date: 2007 Nov 22, 16:39 -0800

    What happens to an image of a celestial body when viewed off center in
    a sextant scope? I have a bad habit of using the lower half of the
    field of view when taking lower limb observations of the sun. I
    suspect that this increases the observed altitude slightly.
