    Are not people driving and walking there all the time?

    This should give a negligible effect.
    I suppose the screen can be just held in our hands.

    My dividers and ruler have much higher precision, definitely better
    than
    0.05 of an inch approx 1 mm.

    This is why Frank mentioned that the telescope has to be good.
    Certainly, I would rather have my inverting one
    for these experiments. But I hope that the prizmatic one from Frank's
    sextant is also good enough.
    
    Alex.
