JMI RB10 Reverse Binocular Telescope - 10"

Are you curious about what a Reverse Binocular Telescope is? Then step inside the ingenious Jim's Mobile RB design which allows 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. JMI Reverse Binoculars are built with two aligned Newtonian optical tubes on an alt-az mount creating a very compact and comfortable viewing experience and the sizes available sizes 6" (RB-66), 10" (RB-10), 14.5" (RB-14.5) and 16" (RB-16). All models feature JMI's celebrated quality construction!

What makes the JMI Reverse Binocular telescope different? Other designs of this type usually involve manual adjustments of some kind for focus, eye spacing and image convergence. This results in a large amount of time needed to get the system set the way you want it. Sometimes it takes two people. Jim's Mobile has motorized all of those adjustments and the total "tweak" time is lowered from one or two hours to one or two minutes. These adjustments are now made by pushing buttons (while you are comfortably seated) and visually watching the results in real time. This is a huge advantage, especially if more than one person is going to be using the instrument.

The portable JMI RB-10 Reverse Binocular telescope 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. The Altitude and Azimuth axis on the JMI RB telescopes operate as smooth as silk and optical encoders can be installed for use with a guiding computer to easily find objects.

The JMI RB-10 Reverse Binocular Telescope weighs approximately 68 lb. and has a height of 58" at Zenith (measured from top of binocular to bottom of tripod with binocular in vertical position). It includes two modified 2" RCF-1 focusers with motors for motorized focusing, two 1.25" 30mm Wide-Angle Eyepieces and a Star Pointer Finder Scope.
