Folded Newtonian Telescope

johanneswilm writes "Michael Fallwell has figured out a way to overcome many of the problems of traditional telescope construction - making it way more compact and economical. And the whole thing is completely portable and achieves accuracy down to one or two millionths of an inch across an 18 inch surface!"

You must be new around here. The correct take off of a Ma$tercard add is:

18" DOB $2200
Mirror Grinder 40" $1800
10" Folded Schmidt Camera $4500

Finding out you spent ALL your money on glass and plastic and are getting kicked out of your apartment. Priceless.

For some things in life there is Slashdot, for everything else there is Google.

I assume the guy doesn't live in an appartment. My 12' Schmidt Cassegrain telescope however, while less interesting that this project, can be moved with a bicycle trailer to go stargazing on the high hill near my place, and doubles as a handy tool to watch my neighbours' boobs in the appt complex down the street.
