Re: ATM Speaking of which.


Not really.  Actually most of them have a little bit softer focus overall
than a good ortho and thus make the needs a little bit less in actuality.
The only demand is for a good sized secondary so that the full EP is
illuminated.  It's also known that the Paracor softens the focus slightly
and that's to be expected if you ever tried designing one.  It IS the nature
of the beastie.
