[sac-forum] Re: Diagonal Size

Jack,

Newt and I are old friends. My shelved 16" was designed with it, and now
my 14.25" f7 (which *will* be built, since I bought the mirror first). 
It is extremely easy to use. I am crunching numbers on it at this very
moment.

BTW, I am looking at an EP height of 99" at the zenith. Ouch! Just like
a 20" f5. It doesn't seem too high until you get out the tape measure.

Thanks, that's good info.

Bartels doesn't explain anything at all to you, but my searching found
this
nifty program and most welcome explanation/illustration:

And I found the site you mention also,
http://home.earthlink.net/~flyj/designie5.html, however
 you may really like the former free/shareware program (It's called Newt
and
you have to download it).
