BALANCING: AZIMUTH/RA
Balancing the Azimuth/RA Axis currently in -
volves two forms of adjustment::
1) Shifting the fork-arm, relative to the Azi -
muth/RA motor, on the bolt-patterns that join
the two assemblies.
2) Attaching counterweights to the 1/4-20
threaded holes on the fork-arms interface
plate (to the base-motor), shown to the right.
In the near future, PlaneWave will offer an
optional balancing accessory system for the
L-350. In the meantime, please start from the
general recommendations below, add weight
as needed and call our technical support staff
for guidance, if needed.
