The precise balancing is carried out by
loosening the
RA clutch. The equilibrium
point is reached by moving the counterweight
on the counterweight shaft. It should not
require much movement, but longer
counterweight shafts and additional
counterweights are available in case more
weight is needed to achieve proper balance.
When balance is established, tighten the
counterweight knob and the RA clutch knob
.
NOTE:
Other mounts, based on geared wheel and worm drive systems, must be slightly
unbalanced in the direction of celestial movement to obtain precise tracking. Such mounts
may require occasional re-balancing by moving the counterweight. In contrast, the M-zero
LHQ mount is well balanced in every position to guarantee the absence of backlash,
hysteresis and pendulum effects around the meridian. This difference proves to be a
significant advantage. Due to the M-zero’s toothed belt transmission system, once balanced,
it is no longer necessary to change the weight position. This is a valuable feature for long
term Astrophotography around the meridian and is essential for the remote use of the mount.
