Subject: True Field By: Anonymous (xxx.xxx.214.71) Date: 07/28/2003 10:33:34 am PST The comment of FOV needs correction: The True Field in the 92mm Stowaway with a 22mm Nagler T4 is NOT 4 degrees. The field stop of the 22mm Nagler is 31.1mm. The focal length of the f/7 Stowaway is actually 604mm (f/6.6) per the AP website. So using the field stop calculation of (31.1/604)*57.3 gives you a TFOV of only 2.95 degrees. The 31mm Nagler yields a true field of 3.98 degrees.

The post about the 22mm Nagler yielding a 4 degree true field is incorrect for the f/7 model. It's close for the old f/5 version, but not the new version. The True Field in the f/7 92mm Stowaway with a 22mm Nagler T4 is NOT 4 degrees. The field stop of the 22mm Nagler is 31.1mm.
