Getting Started! First Steps
Balancing the Telescope
In order for the telescope to be stable on the tripod and also for it to move
smoothly, it must be balanced. To balance the telescope, unlock the Right
Ascension or R.A. lock (33, Fig. 1d). When this axis is unlocked, the tel-
escope pivots on the R.A. axis. Later in the procedure, you will also unlock
the Declination or Dec. lock (17, Fig. 1d). When unlocked, the telescope
pivots on the Dec. axis. Most of the motion of the telescope takes place by
moving about these two axes, separately or simultaneously. Try to become
familiar with these locks and observe how the telescope moves on each
axis. To obtain a fine balance of the telescope, follow the method below:
1. Firmly hold the optical tube secure so that it cannot accidentally
swing freely. Loosen the R.A. lock (33, Fig. 1d). The optical tube now
moves freely about the R.A. axis. Rotate the telescope so that the
counterweight shaft is parallel (horizontal) to the ground.
2. Unlock the counterweight lock knob and slide the counterweight (21,
Fig. 1d) along the counterweight shaft until the telescope remains in one
position without tending to drift down in either direction. Then re-tighten
the counterweight lock knob, locking the counterweight in position.
3. Again, hold the optical tube so that it cannot accidentally swing freely.
Lock the R.A. lock (33, Fig. 1d), and unlock the Dec. lock (17, Fig. 1d).
The telescope now is able to move freely about the Dec. axis. Loosen
the cradle ring lock knobs (13, Fig. 1a) so that the main tube slides eas-
ily back and forth in the cradle rings. Move the main tube in the cradle.
Looking at or near the Sun will cause instant and irreversible damage to your eye!
