Re: [APML] Meade Schmidt; was: High Res M31

["Bert Katzung" <katzung1@attbi.com>]

Hi Jason:
Where is the film loading door for the Meade Schmidt camera? Is it visible
in the shots of it in your observatory? And what size & shape of film do you
use? What kind of film holder does it use to shape it to the focal plane?
Thanks,
Bert
