Re: ATM What is illuminated field?

Olle,

First, I haven't read all my mail yet (6 more to go), but I want to tell
you that I have exactly the same questions: what does "off-axis" mean? 
In which direction, in relation to what, and why?  "%illumination" of
what, and why?  I still have no idea what minimum diagonal size to
choose, or where to position the focuser.  Looking forward the answers
to your questions.  If they're not posted to the ATM group, would you be
kind enough to forward them to me (carlw@telis.org).

Thanks
