36 When the display readout is close to "1" (perhaps .99 or 1.01) and remains close to 1 while it is moving, it is balanced. Press MODE. This stops the Balance procedure.

Next move the telescope so that it is 90° perpendicular to the Home Position. Select Balance RA once again and press ENTER.

Repeat the same procedure in the perpendicular posi- tion. Once again, move the weights to get the balance readouts to get close to 1.

Next move the telescope so that it is 90° perpendicular to the Home Position (see Fig. 36).

Press MODE. Move the telescope to the home position. Position 4 people to hold onto the tube securely and loosen the Dec lock knobs. See Fig. 37.

Move the OTA forward or backward within the female dovetail track and tighten the lock knobs. Move the tele- scope back to the position that is 90° perpendicular to

Dec axis is from "1" in the Dec Balance menu.

Move the OTA back to the Home position. Move the OTA forward or backward again. Continue this procedure, moving back and forth between both the home (Fig. 38A) and the perpendicular position (Fig. 36), and adjust the OTA until the telescope is balanced in this axis. Make sure you tighten the lock knobs after each

38 adjustment of the OTA.

C When the axis is finally balanced, press ENTER. Tighten the lock knobs and turn the Dec Balance hard stop bolt so that it butts up against the OTA plate—it remembers your Dec Balance point. You should not have to balance the telescope again unless you change
