[ATM] Gimbaled Secondary mirror

[<atm@hudler.org>]

Dave,
	Only two axes are needed as long as you rotate about the mirrors
vertex. Frankly I've never understood the reasons behind the three axis
system found on virtually all amateur telescopes (ours included) but I sure
someone will chime in with it. 

LOL I was just searching for gimbals on yahoo's images and this came up;

This will work, but it will need to be folded. I'll model it in Autodesk
Inventor and see if it works.
