[ATM] Wide Scan Type III specs

[John Lynch <john_lynch2005@yahoo.com>]

To the ATM listserv:

Does anyone have the specifications for the field stop
location (relative to the point where the eyepiece
comes to rest in the focuser) for Wide Scan Type III
30mm eyepiece (2")?  I've heard that, like Naglers,
it's internal and therefore a negative distance. 
Also, information regarding performance would be
greatly appreciated off-line.

Thanks.

John Lynch
