QUESTION:
How big are the mirrors on the telescope?

ANSWER from Juan Rivera on October 15, 1995:
There are three mirrors on the telescope.  The primary mirror is one meter in
diameter and about 6 inches thick.  It's made of glass and is very heavy.

The oscillating secondary mirror is about the size of a small dinner plate
and is made of aluminum.

The tertiary mirror is oval shaped and is about 6 inches across by 1 footlong
and about 3 inches thick.  It's also made of glass and is extremelyflat.  Its
flatness is measured in fractions of a wavelength of light.
