Eyepiece Installation
1.
Locate the Wide Angle (25mm) eyepiece and the 45
Degree Correct Image Diagonal.
2.
Remove the rear Dust Cover in the Focuser and place
the Diagonal into the back of the telescope; secure with
the set screw on the side of the focuser. (Figure 9)
3.
Remove the Eyepiece Dust Covers and place the
eyepiece into the diagonal (only the correct direction fits
into the diagonal) and secure with the set screw on the
Diagonal. SAVE THE DUST COVERS FOR PROPER
STORAGE. (Figure 10)

Your First look
Tighten or loosen the Altitude and Azimuth locking bolts ten-
sion control knobs (if needed) so that the telescope is easy to
move, but secure enough to keep the telescope pointed where
you aim it.
Use your hands to move the telescope close to a target, fine
adjustment in the up/down direction can be made by the
Altitude Fine Adjustment Control Knob. Tension in the up/down
direction is controlled by tightening the Altitude Locking Screw
and the Yoke Locking Knobs – if too loose the telescope will
move too freely (it will give "shaky" views); if too tight, it will be
hard to move the telescope.
1.
During the daytime, sight along the tube to a distant,
easily recognizable object and push the telescope
tube (not the tripod) towards that object. With the dust
caps removed, look through the telescope and use the
FOCUS KNOBS to move the eyepiece in-and-out until
the object comes into focus!
