VI . Balancing the Mount in Declination
Telescope Tube with Dovetail Slide Bar
Telescope Tube with Tube Rings
1
Loosen the R.A. clamp lever while holding the counterweight
bar (1-1) and turn the telescope tube until the DEC. axis comes
to horizontal (1-2). Tighten the R.A. clamp lever and loosen the
DEC. clamp lever. Be sure to hold the optical tube or counter-
weight in hand while loosing the clamp levers.
2
Release the telescope gradually to see which way the telescope rotates around the declination axis.
If the telescope tube starts rotating as you release, it shows there is an imbalance in DEC.
To determine the balance point, loosen the lock screw that hold the telescope tube to the dovetail-plate
mounting block and slide the telescope tube either forward or backward until it remains stationary.
3
Tighten the lock screw (and the safety screw) securely to hold the telescope tube in place.
4
Tighten the DEC. clamp lever to finish this adjustment.

To determine the balance point, loosen the tube ring lock knobs that hold the telescope tube and slide
the telescope tube either forward or backward until it remains stationary.

Tighten the DEC clamp lever to finish this adjustment.
CAUTION
CAUTION
Do not loosen the lock screw too much in balancing. This could drop off the telescope tube or lead to injury.
Pay close attention to the security of the telescope tube when you balance the mount.
