I have a XRAY shield which was
manufactured by Questar Part number 19370.

Curiously they call it a counter
weight system.

It could be used to keep pesky beta
and alpha particles (not to mention
some low energy gamma rays) out of
your telescope.

Or you could use it as a counter

If you are planning to use it as a
XRAY shield for your telescope
the price is $1,000,000.

Otherwise, make an offer.

It for $90 now.
It went for $75 when I bought it.

A serial optec temperature compensated
focuser would do as a trade.
