Balancing the telescope

A telescope should be balanced before each observing session. Balancing reduces stress on

the telescope mount and allows precise slow-motion movements. A balanced telescope is especially

crucial when using the optional clock drive for astrophotography. The telescope should be balanced

after all accessories (eyepiece, camera, etc.) have been attached. Before balancing your telescope,

make sure that your tripod is balanced and on a stable surface. For photography, point the telescope

in the direction you will be taking photos before performing the balancing steps.

R.A. Balancing

• For best results, adjust the latitude of the mount to between 15º and 30º if possible, by using the

latitude adjustment T-bolt

• Slowly unlock the R.A. and Dec. lock knobs. Rotate the telescope until both the optical tube and the

counterweight rod are horizontal to the ground, and the telescope tube is to the side of the mount.

• Tighten the Dec. lock knob.

• Move the counterweights along the counterweight rod until the telescope is balanced and remains

stationary when released.

• Tighten the counterweight screws to secure the counterweights.

Dec. Balancing

All accessories should be attached to the telescope before balancing around the declination axis. The

R.A. balancing should be done before proceeding with Dec. balancing.

• For best results, adjust the latitude of the mount to between 60º and 75º if possible.

• Release the R.A. lock knob and rotate around the R.A. axis so that the counterweight rod is in a

horizontal position. Tighten the R.A. lock knob.

• Unlock the Dec. lock knob and rotate the telescope tube until it is parallel to the ground.

• Slowly release the telescope and determine in which direction it rotates. Loosen the telescope ring

clamps and slide the telescope tube forward or backward between the rings until it is balanced.

• Once the telescope no longer rotates from its parallel starting position, retighten the tube rings and

the Dec. lock knob. Reset the latitude to your local latitude.

Using the red dot nder

The red dot nder is a zero magnication pointing tool that uses a coated glass window to

superimpose the image of a small red dot onto the night sky. The red dot nder is equipped with a

variable brightness control, azimuth adjustment knob, and altitude adjustment knob. The nder is

look through the sight tube and move your telescope until the red dot overlaps the object. Make sure

to keep both eyes open when sighting.

Like all nderscopes, the red dot nder must be properly aligned with the telescope before use. This is

a simple process using the azimuth and altitude adjustment knobs.

• Open the battery compartment by pulling down the cover and remove the plastic shipping cover over

the battery.

• Turn on the red dot nder by rotating the variable brightness control clockwise until you hear a click.

Continue rotating the control knob to increase the brightness level.

• Insert a low power eyepiece into the focuser. Locate a bright object and aim the telescope so that

the object is in the center of the eld of view.

• With both eyes open, look through the sight tube at the object. If the red dot overlaps the object,

your red dot nder is perfectly aligned. If not, turn its azimuth and altitude adjustment knob until

the red dot overlaps the object.
