    Re: Optical bench for sextants?

    Hi Ed,
    Nice to see the optical bench device on photos. I've seen it only in textbooks where it was shown only schematically with some description text. I attached a copy from the Russian book written by Krasavtsev. There were two companies making the optical benches: VEB (DDR) and Plath (BRD) which are different only in some details.
    I was always wondering about a modern version of optical bench. Does it exist? On which basis they put all arc errors to zeros in my ASTRAIIIB sextant certificate ...
    regards,

    Igor
