    Re: Cannot focus sextant telescopes
    From: David C

    The spare piece F is clearly an eyepiece. I have confirmed that one eyepiece magnifies and inverts (positive?) and the other reduces size and is erect ( negative?). The explanation that the tube for the Galilean scope is missing makes sense.

    The tube C  has two lenses.

    In five or six days when the cloud clears I will go outside and see if I can focus the Keplerian on the sun.
