ALIGN THE RED DOT VIEWFINDER

Perform the first part of this procedure
during the daytime and the last step at night.
1. Point the telescope at an easy-to-find 

land object such as the top of a telephone
pole or a distant mountain or tower. Look
through the eyepiece in the diagonal
mirror and turn the focuser knob (23) 
until the image is sharply focused. Center
the object precisely in the eyepiece’s field
of view.

2. Turn on the red dot viewfinder using the

switch on the side of the finder.

3. Without moving the telescope, look

through the red dot viewfinder. Turn one or
more of the viewfinder’s alignment screws

3. Slide the MH 25mm eyepiece (1) into
diagonal mirror (13).
4. Tighten the diagonal mirror
thumbscrew to hold the eyepiece

securely.

BALANCING THE OPTICAL TUBE

The telescope is designed with a bracket that
will allow the user to balance the optical
tube. This may be needed when heavier
eyepieces or accessories are used.
1. Loosen the optical tube locks [11] so the

tube will slide in the mounting bracket.

2. Balance the tube by sliding it back and

forth in the bracket until you find a position
where the tube remains horizontal (i.e.,
without tipping up or down).

3. Retighten the optical tube lock knobs to a

firm feel

If the horizontal and/or vertical

movement of the optical tube seems to be too
loose or too tight, you can adjust the amount
of tension in the movement of the tube to suit
your own preferences.

(3) until the red dot is precisely over the
same object as you centered in the
eyepiece.

4. Check this alignment at night on a

celestial object, such as the Moon or 
a bright star, and use the viewfinder’s
alignment screws to make any 
necessary refinements.

TO MOVE THE TELESCOPE

Your telescope is altazimuth mounted.
Altazimuth is just a complicated way of
saying that your telescope moves up and
down and from  side to side. Other
telescopes may be mounted in 

Looking at or near the 

Sun

will cause 

irreversible

damage to your eye. Do not point this telescope at or near the Sun. Do not look through the telescope as it is moving.
