SUN WARNING
NEVER USE YOUR TELESCOPE
TO LOOK AT THE SUN!
LOOKING AT OR NEAR THE SUN WILL CAUSE
INSTANT AND IRREVERSIBLE DAMAGE TO YOUR
EYE. EYE DAMAGE IS OFTEN PAINLESS, SO
THERE IS NO WARNING TO THE OBSERVER THAT
DAMAGE HAS OCCURRED UNTIL IT IS TOO LATE.
DO NOT POINT THE TELESCOPE OR ITS VIEW-
FINDER AT OR NEAR THE SUN. DO NOT LOOK
THROUGH THE TELESCOPE OR ITS VIEWFINDER
AS IT IS MOVING. CHILDREN SHOULD ALWAYS
HAVE ADULT SUPERVISION WHILE OBSERVING.
phone pole or a distant mountain or tower.
Look through the eyepiece in and turn the
focuser knob (21) until the image is sharp-
ly focused. Center the object precisely in
the eyepiece’s field of view.
2. Turn on the red-dot viewfinder by rotating
the large knob under the viewfinder lens
clockwise (10). Turn the knob to adjust the
intensity of the red dot as desired.
3. Look through the viewfinder. Turn one or
both of the viewfinder’s alignment screws
(3) until the red-dot is precisely over the
same object as you centered in the eye-
piece.
4. Check this alignment at night on a ce-
lestial object, such as the Moon or
a bright star, and use the viewfinder’s
alignment screws to make any necessary
refinements.
5. When finished, turn off the viewfinder
by turning the large knob (10) under the
viewfinder lens counter-clockwise until it
clicks.
TO MOVE THE TELESCOPE
Your telescope is alt-azimuth mounted.
Alt-azimuth is just a complicated way of say-
ing that your telescope moves up and down
and from side to side. Other telescopes may
be mounted in different ways.
1. To move the telescope in the horizontal
direction (azimuth), slightly loosen the
horizontal lock knob (5). Loosening this lock
allows the telescope to be moved from side
to side.
2. To move the telescope in the vertical direc-
tion (altitude), use the pan handle on the
rear of the mount to make coarse adjust-
ments. Note the vertical direction does
not have a locking knob and can be
moved at any time.
3. Once an object is found, re-tighten
the horizontal lock knob (5). You can
then rotate the slow motion controls
(11 & 12) to make smooth and precise
movements and follow (or “track”) an ob-
ject horizontally and vertically as it moves
in the eyepiece.
THE MOST IMPORTANT RULE
We have one very important rule that you
should always follow when using your tele-
scope:
