Wait until you see the real thing... :-)

The Keystone Telebinocular used to be my favorite viewer.  I do not
wear glasses so I enjoy the isolation offered by the hood.

Until.... I discovered the "Visual Survey Telebinocular" and the visual
pleasure of the achromatic lenses.  Even though the two scopes are
called "Telebinocular" there are very different.  The simple "Keystone
Telebinocular" is a portable scope with simple lenses.  The "Visual
Survey" is a tabletop viewer with achromatic lenses, adjustable height,
wide opening for glasses, forehead support, internal illumination, etc.
It was sold for eye exams.  Alan Lewis has made a portable scope that
also has achromatic lenses.  He even made a tight hood for me.  These 
are the two stereoscopes I have kept.  I sold all the plain 
"Telebinoculars".  Long live the achromatic scopes!
