    Dear Jeremy,

    I envy you:-) A cargo ship?

    I am a Lunarian, in the sense that 99% of my observations
    are Lunars taken from land:-(
    I have an SNO-T which Freiberger people call "our clone"
    and I have absolutely no inconvenience reading the 1' drum to 0'1.
    
    However, SNO-T has a great feature which facilitates this:
    a strong magnifying glass.
    With this glass, it is easy to interpolate the 1'
    divisions to 0.1', even in twilight.
    
    The magnifying glass (and the drum itself) also has a luminous coating
    which allows you to read in comlete darkness, without any batteries
    or wires.
    
    In general, many features of this "Freiberger clone" look like if it was
    specially made for Lunar observations:-)
    
    Alex.
