I don't now how they've actually done it, but a possibility you seem to be
overlooking is using several different types of panels. No single panel would
pass the full spectrum, but the overall effect would be the full spectrum, but
somewhat dimmer than with no glass.

understanding of astronomy is purely at the amateur level (or below). So
unless what I'm saying is directly related to VAX/VMS, don't hold me or my
organization responsible for it. If it IS related to VAX/VMS, you can try to
hold me responsible for it, but my organization had nothing to do with it.
