    Yes please. If you already have them in "soft format" I would appreciate
    having them.
    The weekend is coming up so should have a some time to check this out. I
    used this telescope to take star sights on my Atlantic crossing, but having
    used the normal scope for sun sights, and being used to a normal scope it
    was quite difficult to bring star to horizon. I had to consciously
    countermand what my brain was telling me to do.
    My Russian sextant is not WW 1 it is a SNO-T Year 1983  serial no 83376.
