b
Declination (Dec.): Controls the manual movement of the telescope. Turning the Dec. lock counter-
clockwise unlocks the telescope enabling it to be freely rotated by hand about the Dec. axis. Turning
the Dec. lock clockwise (to a firm feel only) tightens the lock and prevents the telescope from being
moved manually, but engages the Dec. motor drive for Handbox operations.

Polar Viewfinder Cap: Remove this cap when using the polar viewfinder.
d
Dec. Setting Circle
e
Counterweight Shaft Base: Thread, along with the shaft, to the mount.
f
Counterweight and Counterweight Lock Knob: Counterbalances the weight of the optical tube, and
adds stability to the mount. Tighten the lock knob on the side of the counterweight to a firm feel to prevent
the weight from sliding on the shaft.
G
Counterweight Shaft: Slide the counterweight onto this shaft.
h
Counterweight Safety Cap: Prevents the counterweight from accidentally slipping off the end of the
counterweight shaft.
