2. Look through the red dot viewfinder. Turn
one or more of the viewfinder’s alignment
screws (3) until the red dot is precisely
over the same object as you centered in
the eyepiece.
3. 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 RB-60 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
different ways.
1. Slightly loosen the vertical locking lever
(5). Loosening this lever allows you to
move the telescope up and down.
2. Slightly loosen the horizontal lock knob
(6). Loosening this lock allows the
telescope to be moved from side to side.
3. Once an object is found, re-tighten the
knob. You can then use the slow motion
controls to make smooth and precise
ATTACH THE DIAGONAL MIRROR
AND EYEPIECE
The diagonal mirror reflects the light
from the optical tube to a more
comfortable viewing position for
the eyepiece.
1. Slide the diagonal mirror into the focuser
drawtube.
2. Tighten the drawtube thumbscrew to hold
the diagonal mirror securely.
3. Slide the 25mm eyepiece into diagonal
mirror.
4. Tighten the diagonal mirror thumbscrew
to hold the eyepiece securely.
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.

movements as you follow (or “track”) an
object as it moves in the eyepiece.
THE MOST IMPORTANT RULE
We have one very important rule that
you should always follow when using
your telescope:
Have Fun!
Have a good time when you’re observing. You
may not know everything that there is to
know about a telescope or what all the
sights in the universe are, but that’s OK. Just
point and observe at first.
