◆ Balancing
After the tube assembly has been attached on the mount, the next step is to balance it in
the R.A. and Dec. axes. If unbalanced, the clamps will not work effectively and the tube
assembly will abruptly and dangerously turn. When the motor of the mount is rotating,
unbalancing will cause gearing trouble that will make the life of the mount shorter. When
balancing, do it with all accessories necessary for observation attached to the tube
assembly.
▼Balancing around the Dec. axis
1. Loosen the Dec. clamp and lock it at
the position that the Dec. axis becomes
horizontal.
2. Loosen the handle of the dove-tail
adapter (F) and move the tube assembly
forward and backward until it balances.
In the normal visual observation, place
the tube assembly at the top of the dove-
tail adapter as illustrated.
▼Balancing around the R.A. axis
1. When balancing around the Dec. axis
has been made, lock the Dec. clamp
firmly.
2. Loosen the R.A. clamp and see balancing
around the R.A. axis.
3. If unbalanced, move the counter-weight
until it balances and lock the R.A. axis.
4. If unbalanced at the top of the counter-
weight shaft, add an extra weight to
balance.
