Re: [ATM] Illuminated Field - How Much?

Currently using a 1.6" focuser. Actually, need to move the other 
direction. The problem is the binoviewer is already too close in and 
reaches too far into the tube. The focal plan needs to be pushed out 
about 1". Page 91 of the March 05 issue of Sky and Telescope has a 
photo illustrating the problem.
