Red dot nder

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

pose 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 powered by

a 3-volt lithium battery located underneath at the front.

To use the red dot nder, simply 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.

Balancing the telescope

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

scope 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 direc-

tion you will be taking photos before performing the balancing steps.

R.A. Balancing

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

altitude 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

altitude 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 bal-

anced.

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

and the Dec. lock knob. Reset the altitude axis to your local latitude.

Eyepiece assembly

• Unthread the thumbscrews on the focuser tube.

• Insert the diagonal mirror into the focuser tube and secure it by retightening the thumbscrews.

• Unthread the thumbscrews on the diagonal mirror.

• Insert the desired eyepiece into the diagonal mirror and secure it by retightening the

thumbscrews.
