    Greg, thank you for the idea.

    I tryed to look into the instrument via a half of a binocular (prismatic, 40x6, I think). I was surprized to NOT see the same thing that I see by naked eye: there were no two distinct halves of the image (one direct, another reflected). I saw a superimposed image without a left-right separation! At first I thought that my binocular looks past the instrument, but no, it was properly alligned.

    After reading some more articles in Bill Morris' blog I discovered that telescopes come in two varieties - Keplerian and Galilean. The first type gives an intermixed image while the second type keeps the image separation (this is how I understood the article).

    The FREIBERGER's documentation clearly states that the Galilean scope should used with the instrument.


    A lot of interesting and amazing new things one may discover while studying Celestial Navigation!
