ATM 22" binocular design

["Bruce Sayre" <sayre@foothill.net>]

A page describing a portable 22", f5 Newtonian binocular telescope's design has been added
to my Web site (see URL below). I'd appreciate any feedback that list members would care
to volunteer before starting construction.

These were some of the design objectives:
1. Minimize zenith eyepiece height as much as possible
2. Use 1-1/4" and 2" eyepieces
3. No Barlow or relay lenses
4. Allow 2" eyepieces to touch at the minimum interpupillary setting
5. Keep the minimum interpupillary setting under 2" when using 1-1/4" eyepieces
6. Provide a way to adjust binocular parallelism at the eyepieces after setup
7. Lift and carry all components (no ramp or wheelbarrow)

The binocular shares many parts with a 22" monocular Newtonian, also described.
