Use the 5mm hex key to loosen the M6 socket head cap screw on each side of the mount base. Loosen the two

M12 socket head screws on each side of the mount using the 10mm key provided. If your scope is mounted,

support its weight with your other hand since you are loosening a critical bolt.

Your goal is to sight Polaris when looking through the polar alignment sight hole in the center of the polar axis. You

will need to make altitude and azimuth adjustments to the position of the mount.

Azimuth adjustments: Move the entire pier

or tripod east or west until the mount is

oriented approximately towards the pole (an

imaginary line drawn through the hollow

shaft). Use the two fine azimuth adjustment

knobs, one on each side of the mount, to

make adjustments. You must back off the

opposing azimuth knob in order to move the

other knob in that direction.

Altitude (latitude) adjustments: Move the

polar axis up or down with the large altitude

adjustment knob located at the rear of the

mount assembly. We have found that using

the turnbuckle on the north leg of our pier

also can make fine altitude adjustments, if

used.

Continue your azimuth and altitude

adjustments until you can sight Polaris in the polar alignment sight hole. At this point, you have achieved rough

polar alignment, which may be sufficient for casual visual observations, if you are not planning to slew to target

objects with the keypad. When the R.A. motor is engaged (the power cord is plugged in), it will compensate for the

rotation of the earth and keep the target object within the eyepiece field of view. Your target object will slowly drift

since polar alignment at this stage is only approximate. However, you can make corrections with the N-S-E-W

buttons of your keypad controller.

Snug the two M6 socket head cap screws and two M12 socket head cap screws to lock the mount into position.

You will complete your polar alignment and calibrate on a star with your keypad controller when your telescope is

completely setup and you are ready to observe.

Assemble Cradle Plate

Several mounting plates are available for the 600E mount. If you own more than one instrument, you may need more than

one plate. Attach your mounting plate with the screws provided. It is important to use the proper screws, please refer to the

"Mounting Plate Fastener Chart" included with this manual.

Assemble Counterweight Shaft

IMPORTANT: Always attach the counterweights before mounting the telescope to the

cradle plate to prevent sudden movement of an unbalanced tube assembly which may

cause damage or injury. Remember counterweights are heavy and will hurt if they fall on

your foot.

Thread counterweight shaft onto the Dec. axis.

Remove the hand knob and washer from the base of the counterweight shaft. Add sufficient counterweights (6 or 9

lb. counterweights are available) to the counterweight shaft to balance the telescope you intend to use. Always use

two hands to attach or move 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.

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 counterweights.

Attach Mounting Rings

Our flat plates are constructed with keyhole slots at the location where your mounting rings attach. This feature enables you

to partially loosen the screws on your rings just enough to insert them into the larger part of the keyhole, then slide the rings

to the narrow part and tighten them with a hex key. You can even accomplish this with the rings on the scope, although this
