VISUAL GUIDE

Extend the legs (Q) as shown in Fig.1, and lock them at the
desired height using the wing nut (1) supplied.
Connect the three legs to the tripod head (O) using the wing nut
and the bolt (2), proceeding as shown in Fig. 2a.
Then attach the accessory tray (P) to the flanges of the tripod legs
using the adjustment nuts and bolts supplied (see Fig. 3).
Once all of the bolts have been tightened down fully, the tele-
scope's main body can be attached to the tripod head yoke (M).
Proceed as shown in Fig. 2b: mount the telescope's main body (H)
in the yoke (M) and adjust it using the large locking screw (K).
Then tighten down the yoke screw (see Fig. 2b and 2c).
Remove the finderscope (G) with the attached bracket (F) from its
box.Then remove the two knurled thumbscrews from the tele
scope's main body (H). Locate the finderscope bracket on the tele-
scope's main body so that the holes drilled in the bracket base line
up with those exposed in the telescope's main body. Refit the two
knurled thumbscrews and tighten them down securely
(see Fig. 4).
Insert the angle prism (D) into the focusing tube (C). Hold it in
place by tightening down the corresponding mounting bolts
(see Fig. 5).
Fit the eyepiece (E) into the angle prism (D).The eyepiece also
requires adjusting using the small tightening screw (see Fig. 6).

INSTRUCTIONS FOR USE

FINDERSCOPE ADJUSTMENT
As the telescope only offers a limited field of view, it may be fairly
hard to locate a given star or planet for observation.This is why the
telescope is fitted with a cross-hair finderscope for orientation
purposes.We recommend performing the following adjustments
in daylight.
1)
2)
Insert the eyepiece with the lowest magnification factor into
the angle prism connector. Observe an easily recognizable fixed
object that is no more than 300 meters away. Swivel the telescope
through its horizontal axis and adjust it along the vertical axis until
the object is located right in the center of your field of view, then
immobilize the telescope by tightening it down securely.
Now look through the finderscope. If the object seen through the
telescope cannot be seen, slacken the adjusting nut and move
the finderscope until you can see the object.Then tighten down
the adjusting nut making sure that the object remains visible in
the center of the finderscope.To simplify this procedure, use the
adjusting nut to position the object in the center.The finderscope
will move in the direction in which the nut is turned. As soon as the
eyepiece adjustment coincides with that of the finderscope, all of
the nuts can be finally tightened down.

ALTITUDE-AZIMUTH MOUNT
The telescope is fitted with an Altitude-Azimuth mount.“
Altitude ”refers to the telescope's up and down or vertical movement,
while“Azimuth” refers to its sideways or horizontal movement.
The Altitude Azimuth mount used in conjunction with the microad-
justable Altitude control and Azimuth Lock (N) lets you see the entire
night sky or any celestial body without having to move the tripod.
Which magnification should be chosen?
SELECTING A SUITABLE EYEPIECE
The magnification defines the telescope's ability to enlarge an image
or to bring it closer in order to see it better.
800 mm focal length
Example: = 40x magnification
eyepiece focal length 20 mm
The required degree of magnification depends on the object to be
observed.
To this end, we recommend conforming to the following general
guidelines:
Ideal viewing conditions are obtained when the magnification
factor corresponds to no more than 15 to 20 times the lens diameter,
i.e. the optimal magnification of 100x to 125x obtained with a 60 mm
diameter lens makes it possible to observe most celestial bodies.
We recommend using a lower magnification factor for
observing the stars as the field of view will be wider so that the object
being observed will be easier to locate.The highest magnification
factor should only be used for especially finely detailed observations
of the moon.This is because the moon is relatively close and excep-
tionally bright, so that good detail resolution is obtained even with a
high magnification ratio.

GENERAL CONSIDERATIONS
Avoid sudden temperature fluctuations likely to cause any dampness
in the air to condense on the telescope's lens. If this phenomenon
occurs, place the lens at a moderate distance away from a heat source
and let the dampness evaporate away progressively.
Warning: To avoid any eye injury never look directly into another
optical instrument through the telescope and never observe the sun
with unprotected eyes!
