    Re: How does the AstraIIIb split mirror work?

    With a simple experiment Jim should be able to see how much the clear
    part of the horizon glass is responsible for what he's seeing. Simply
    cover that half with dark paper, so only the silvered glass can
    reflect rays back to the telescope.
    
    I would be interested to hear the results.
