The telescope is now properly oriented. This
procedure is necessary for tracking celestial
bodies.
6. Tracking- and/or Observation Position
Loosen the vertical clamp (8) and tilt the tele-
scope tube 90° downwards. Loosen the hori-
zontal clamp (33) and turn the telescope 180°
to the right or left, until the objective lens is
pointing in the direction of the sky.
Retighten all clamps so that you can track with
the flexible shaft.
The manual operation of the counterweight
axis (right ascension axis, R.A. axis) via the
flexible shaft (26) allows for the rotation of the
Earth in such a way that the positioned object
always stays in the eyepiece field of vision.
If you would like to switch to another object,
loosen the clamps, swing with the tube in the
proposed direction and retighten the clamps.
The fine adjustment is then performed with the
flexible shafts (14, 15) (Figures 1).
7. Finder
Your telescope is now roughly aligned and set
up.

In order to obtain a comfortable observation
position, carefully loosen the screw on the tube
clamp (8) (Figure 1) so that you can turn the
telescope tube. Bring the eyepiece and the fin-
derscope into a position from which you can
observe comfortably.
The fine adjustment happens with the help of
the finderscope (2). Look through the finder and
try to hone in on, for instance, the North Star
(Figure 16), positioning it in the middle of the
finder's crosshairs (Figure 17). For the exact
adjustment, the shaft of the counterweight axis
(26) as well as the shaft of the declination axis
(27) will be helpful.
8. Observation
After you have located the North Star in the fin-
der, you will be able to recognize the North Star
when you look through the eyepiece of the tele-
scope. If needed, you can angle the telescope
even more exactly toward the star (with the help
of the flexible shafts), or you can adjust the fo-
cus with the focus knob (7) (Figure 1).
Additionally, you can now switch to a higher
magnification by changing the eyepiece (to a
smaller focal width). Please be aware that the
magnification of the stars is barely perceptible.

TIP:
Eyepieces are lens systems designed for your
eye. In an eyepiece, the clear image that is gene-
rated in the focal point of a lens is captured (in
other words, made visible) and magnified still
more. Eyepieces with various focal widths are
necessary in order to achieve various degrees of
magnification. Begin each observation with an
eyepiece with a low magnification (= large focal
width, e.g. 20 mm).
