Viewfinder Bracket Screws (2): Tighten to a firm feel to hold viewfinder secure-
ly in place (see
E
). See page 12 for more information.
1^
Focus Lock Knob: Designed to prevent the focuser drawtube from moving when
a heavy accessory, such as a camera, is attached to the focuser assembly. For
normal observing with an eyepiece and diagonal, it is not necessary to use the
lock knob.
1&
Dec. Lock: Controls the manual movement of the telescope. Turning the Dec.
lock counterclockwise 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 (see
3$
) for Autostar operation.

Polar Viewfinder Cap: Remove this cap when using the polar viewfinder (see
2(
).

Declination (Dec.) Setting Circle: See
APPENDIX A
, page 48, for more informa-
tion.

Counterweight Shaft Base: Thread, along with the shaft, to the mount. See
page 11 for more information.

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.
2@
Counterweight Shaft: Slide the counterweight onto this shaft (see
2!
).
2#
Counterweight Safety Cap: Prevents the counterweight from accidentally slip-
ping off the end of the counterweight shaft.

Computer Control Panel (see Fig. 1e):
A. Handbox (HBX) Port: Plug the Autostar or EC handbox coil cord (10,
Fig. 2) into this port.
B. 12v DC Power Connector: Plug the battery pack into this connector.
The telescope assembly also may be powered from either a 12v DC
auto cigarette lighter plug using the optional #607 Cigarette Lighter
Adaptor or from a standard 115v AC home outlet using the optional
#547 Power Adapter with Cable or #547F Power Adapter for 220v out-
lets. See
OPTIONAL ACCESSORIES
, page 38.
C. LED: Illuminates when power is supplied to the Autostar or EC hand-
box and the telescope’s motor drive.
D. ON/OFF Switch: Turns the Computer Control Panel and Autostar ON
or OFF.
E. AUX Port: Provides connection for current and future Meade accessories.
See
OPTIONAL ACCESSORIES
, page 38.
F. Dec Port: Plug the coil cord from the Dec. motor assembly into this port
for Autostar to control the motor drive.

R.A. Motor Drive Assembly: Controlled by Autostar or EC handbox. Moves the
optical tube along the R.A. axis. The R.A. Lock (see
3#
) must be tightened to a
firm feel in order for the R.A. motor to operate.
2^
Latitude Adjustment (2): Sets the latitude of your observing location. The two T-
handle screws work in a "push - pull" operation—as you tighten one, loosen the
other. The T-handle above the star marking on top of one of the tripod legs is the
North T-handle screw (South in the Southern Hemisphere). The leg marked with
a star must be pointed North (South in the Southern hemisphere) during the polar
alignment procedure.
2&
Fine Azimuth Control Knobs: Fine tune the side-to-side movement of the tele-
scope when centering Polaris in the telescope eyepiece or when using the polar
alignment viewfinder (see
2(
).
2*
Latitude Dial: Set the latitude of the observing site on this dial using the latitude
T-handle screws. For more information see Step 6, page 12.
Caution When loosening
the Dec. lock, be sure to
support the optical tube
(18, Fig. 1a). The weight of
the tube could cause the
tube to swing suddenly.
