Subject: Re: [APML] f/8 Mirror
Lens...
Has anyone ever tried using one of the 500mm f/8 mirror
lenses for astrophotography? They seem to be relatively inexpensive and allot
of manufacturers have them.
Thanks, Jim Ives
These lenses look attractive for astrophotography, but
everyone I have spoken to about them complain of lousy focus, particularly
on the edges of the image.
