    Hello,
    
    Just curious - how fast was Chandra moving in the telescopic field?  At
    74,000 kilometers, I would think that it would not move much faster than
    the "fixed stars" when one's telescopic tube is "stationary".  I can't
    see such distant objects due to excessive light pollution, and a limited
    aperture on my telescope.
