    Cannot focus sextant telescopes
    From: David C
    Date: 2016 Aug 1, 20:14 -0700

    I cannot get my sextant telescopes to focus.  I have attached a photo of the telescopes and fittings.

    In particular I am puzzled by the lens labelled F. It has male threads on both sides. The threads are of different diameters. Despite trying every possible combination I cannot work out how it is meant to be used. I am wondering I am missing a tube with a female thread at one end, although there aren't any empty slots in the case.

    Any help with a Sextant Telescopes 101 would be appreciated.
