Yes, I did. It was my first mirror. (But I attribute whatever
success Ive achieved to my excellent teacher, Jane Houston.) The
ATM wizards at Chabot Observatory near here say it is at least 1/10
wave but their tester isnt good enough to tell any more than that :-)
The rest of the scope is very straightforward Dob/Newt along the
lines described in Richard Berrys book "Build Your Own Telescope".
