TIP:

Eyepieces are lens systems designed for your 
eye. In an eyepiece, the clear image that is ge-
nerated 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 de-
grees of magnification. Begin each observati-
on with an eyepiece with a low magnification 
(= large focal width, e.g. 20 mm).

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 te-
lescope  tube  90°  downwards.  Loosen  the 
horizontal 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  finderscope  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 ex-
act 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 
finder, you will be able to recognize the North 
Star  when  you  look  through  the  eyepiece  of 
the  telescope.  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 focus 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 perceptib-
le.
