Congratulations on purchasing your new JMI Dobsonian
Wheeley Bar! JMI Wheeley Bars – Meade 10/12 Inch
Dobsonians create an easy way to move mounted telescopes to
and from observing locations. This is a customized model with
four large 10″ all-terrain pneumatic wheels and a tow handle,
consisting of a sturdy base with locking wheels and leveling
bolts. Easily move, lock and level the complete telescope
assembly from location to location without the need to
disconnect and reconnect all the electrical and computer
cabling during transport.
Compatible with:
•Meade LightBridge 10″ / 12″ (Due to variations in
foot placement on the 10″ LightBridge, one or
more of the feet on the base of the scope
may need to be moved in order for this scope to
fit)
•Apertura AD12
•Orion SkyQuest XT12 / XX12 (Some modification is
neeeded to make the Go-To scopes fit due to
placement of four nuts on the azimuth bolt
mounting plate (bottom of scope/ground board).
•Sky-Watcher 12″
•Zhumell 10″ / 12″
•Adaptable to other Dobsonians with 26″ Diameter
Ground Board. Again, sometimes ground board
feet must be moved.
Note: The heavier the telescope mounted on the Wheeley
Bars, the more careful one must be in moving the
complete system by pulling or pushing below the center of
gravity. JMI is not responsible for incorrect loading or
operation.
