RE: [ATM] considering different design

["Jerry Reddell" <jerry.p.reddell63@sbcglobal.net>]

My major objection is that the design requires a flat mirror which is as
large or larger than the primary with the associated grinding, polishing,
and coating effort and costs.

I should start by saying I am fairly new to ATMing. I know most of you say
to start with a newtonian but I stumbled across this page
(www.customopticalsystems.com) and I feel the design is simple enough to
build. I am wondering if the prices he set for optical sets (under the ATM
section) are reasonable given that they are in canadian dollars? Or should I
attempt to polish the optics myself?
Another way to ask the question is can I build a better planetary telescope
for the same price?
