them on the shaft. Reattach the hand knob and washer to the end of the counterweight shaft. This will help to

prevent injury if someone accidentally loosens the counterweight hand knob.

NOTE: A firm tightening of the counterweight knob will not damage the surface of the counterweight shaft.

The pin that tightens against the stainless counterweight shaft is constructed of brass. Likewise, the bronze

sleeve that has been press fit into the center of the counterweight will prevent marring of the shaft as you

move the counterweight up and down.

OPERATION OF THE MOUNTING:

The mounting has a set of clutches on both axes.

Right Ascension Axis Clutch: The knob on the top of the polar axis is the clutch for that axis. The R.A. motor

will not drive the R.A. axis unless it is engaged. Avoid excessive pressure when tightening the knob.

Declination Axis Clutch: The knob just below the cradle plate is the clutch for the Dec. axis. The Dec. motor will

not drive the Dec. axis unless it is engaged. Avoid excessive pressure when tightening the knob.

For proper operation, the telescope must be adequately counterbalanced. Start by balancing the tube assembly.

Tighten the R.A. clutch knob and loosen the declination axis knob so that the telescope tube rotates on the

declination axis. Slide the tube up or down in the cradle rings until it stays put with no clutch drag. Now, tighten

the declination axis and loosen the R.A. clutch knob. Move the counterweights up or down to achieve balance in

R.A. Remember to allow for the extra weight of diagonals, eyepieces and finder scopes. If the scope moves by

itself, even when the clutches are loose, the scope is not counterbalanced properly. Note that a small amount of

imbalance on the East side of the mount is permissible and even desirable for astrophotography and imaging.

Drive Rotation: If you are operating the 600HDA north of the equator, the HEMISPHERE switch must be set to

"N". If south of the equator set the switch to "S".

OPERATION OF THE 8010 CONTROLLER:

The push button controller contains all the circuitry for the two motors. Please refer to Diagram 5.

Power Cord: Attach the 3-pin power cord to the mount and plug the other end into your car's cigarette lighter or

into a 12-volt portable battery pack. Plug the R.A. control cable into the controller's right-hand jack (as seen from

above). Plug the Dec. cable into the left-hand jack. No damage will result from reversing the cables. The

controller simply will not operate. With the cables in place, one of the lamps will light to indicate operation. It is

not necessary to attach the Dec. cable to the controller to run the R.A. axis.

Push Buttons: The four red buttons are arranged so that the left and right buttons control the right ascension,

and top and bottom buttons control the declination. This is the normal orientation of objects in the eyepiece. The

buttons may be used to move an object to the desired location in the field, or to keep a guide star on a crosshair

by making tiny guiding corrections.

Pushing the upper button will cause the object to move "up" in the eyepiece field. If the star moves down when

you push the "up" button, move the DEC switch into the other position. Pushing the right-hand button will cause

the star to move to the right. If it moves to the left, move the RA switch to the other position. When properly set

up, the controller buttons will cause the object to move according to your commands.

Mode Switch: There are two guiding modes (rates), 2x guide and 8x slew rates. The slew rate is for positioning

objects in the field, the guide rate is for fine-guiding at high powers during astrophotography. Move the switch to

select the mode that you prefer.

Select Button: The controller has a select button with 4 LED indicators that allow you to choose the driving rate.

Three of them are internally set for SID (sidereal), SOL (solar) and LUN (lunar). The VAR (variable) is adjustable

with the right hand knob. When you push the SELECT button, one of the LEDs will light up, indicating your

selection. Push the button again and the LED to the left will light. When you begin each observing session, the
