[ATM] Re: Mercury Mirror

[Daniel Reinders <danreind@shaw.ca>]

I missed most of these posts on this thread, so I'm not sure if this was
meant to be ironic or not, but just in case there actually is a group here
in Vancouver that is developing a rather big spinning mercury mirror
observatory

A good solution, if you don't mind only being able to look straight up.

Cheers,

Dan Reinders
