In order to properly use your telescope, you will need to move your
telescope manually at various portions of the sky to observe different
objects. To make rough adjustments, loosen the R.A. and Dec. locking
knobs slightly and move the telescope in the desired direction. To make
fine adjustments, when the knobs are locked you turn the slow motion
control cables.
Both the R.A. and Dec. axis have locking knobs to clutch down each axis
of the telescope. To loosen the clutches on the telescope, unlock the
locking knobs.

To eliminate undue stress on the mount, the telescope should be properly balanced around the polar axis. In
addition, proper balancing is crucial for accurate tracking if using an optional motor drive. To balance the mount:
1. Release the R.A. lock knob (see figure 2-24) and position the telescope off to one side of the mount (make sure
that the dovetail mounting bracket knob is tight). The counterweight bar will extend horizontally on the
opposite side of the mount (see figure 2-25).
2. Release the telescope — GRADUALLY — to see which way the telescope “rolls” or falls.
3. Loosen the counterweight locking knob on the counterweights (one at a time if you have two counterweights)
while holding the counterweight(s) and slowly release them.
4. Move the counterweight to a point where they balance the telescope (i.e., it remains stationary when the R.A.
lock knob is released).
5. Tighten the locking knobs to hold the counterweights in place.

The telescope should also be balanced on the declination axis to prevent any sudden motions when the Dec. lock
knob (Fig 2-24) is released. To balance the telescope in Dec.:
1. Release the R.A. locking knob and rotate the telescope so that it is on one side of the mount (i.e., as described in
the previous section on balancing the telescope in R.A.).
2. Lock the R.A. locking knob to hold the telescope in place.
3. Release the Dec. locking knob and rotate the telescope until the tube is parallel to the ground (figure 2-26).
4. Release the tube — GRADUALLY — to see which way it rotates around the declination axis. DO NOT LET
GO OF THE TELESCOPE TUBE COMPLETELY!
5. For the 70EQ, 80EQ, 114EQ, and 127EQ --- while holding the optical tube with one hand, loosen the knurled
screws that hold the telescope tube inside the tube rings and slide the telescope either forwards or backwards
until it remains stationary when the Dec. lock knob is released. There is no adjustment for the 60EQ as it is
fixed in place on the mounting bracket of the mount.
6. Tighten the tube ring screws firmly to hold the telescope in place.
