INSTRUCTIONS FOR TELESCOPE MODELS 5TN / 54TN / 2TPN
1.
Remove tripod (N) from box.
2.
Stand tripod and spread legs.
3.
Remove telescope main body (I) from the box. Unscrew mounting bolt (B) from telescope base
(5TN) or remove from the box (54TN). Place telescope onto tripod mount (Fig. 1). Insert bolt
through tripod mount (Fig. 1c) and tighten securely.
4.
Remove the finderscope (Fig. 1a) from the box. Place the finderscope (H) in the finderscope bracket
(G) and secure with three finderscope bracket set screws.
5.
Model 5TN: Insert diagonal into the focus tube (Fig. 4m). Secure by tightening small retaining
screws.
6.
Model 5TN: Use the micro-altitude adjusting knob (Fig. 1d) and the azimuth adjusting knob (Fig. 1e)
in the tripod mount to move the telescope as desired.
NOTE: Diagonal is only to be used in combination with the eyepieces (oculars).
7.
Model 5TN: Insert eyepiece (Fig. 4k) into diagonal (Fig. 4m). Secure by tightening small retaining
screw.
NOTE (5TN): In all astronomical telescopes, the image appears upside down. With the use of
the diagonal the image appears erect but with a left to right inversion (mirror like). To use the
telescope for terrestrial viewing and to correct the mirrored image, remove the diagonal and
replace with the erecting eyepiece.
8.
To obtain focus on models 2TPN and 54TN push or pull the focusing tube (D) until the image is
sharp (Fig. 2).
The telescope is now fully assembled and ready for use.
