    Re: Getting to know a sextant.
    From: Tony Oz

    Hello!

    Is my understanding correct:- the optical axis of a telescope should be:

    • parallel to the sextant frame (i.e. - no collimation error)
    • level with the horizon's mirror transparent/reflective border

    How important is it to have the proper frame-to-axis distance (the point #2 above)?

    Regards,

    Tony
