Jims Mobile, Inc. (JMI) - RB66 6 inch Reverse Binoculars

What are REVERSE BINOCULARS?

The Reverse Binoculars (RB-66) allow you to look down into the eyepieces, either sitting or
standing, to see what is in the sky behind you, instead of straining to look up as is the case
with normal binoculars. They are built with two aligned 6″ (f/5) Newtonian optical tubes on
an alt-az mount creating a very compact and comfortable viewing experience. The instrument sits on
a Celestron tripod. (U.S. Patent Pending)

What is an ALT-AZ MOUNT?

The RB-66 includes an altitude-azimuth mount. Altitude-azimuth is sometimes abbreviated as
alt-azimuth or just alt-az. An alt-az mount moves in altitude (up and down) on a horizontal axis
and in azimuth (left and right) on a vertical axis like a gun turret on a tank. By comparison, an
equatorial mount is essentially an alt-az mount that is tilted to match your latitude, allowing a
telescope to track the stars with the addition of a simple clock drive. Both types of mounts have
their advantages. Which one is best for a particular situation depends mostly on how one intends
to use the telescope.
