Look  through  the  telescope  and  place  it  on  position  on  the  top  of  the 
tower. 

 

 
 

Look  through  the  viewfinder  tube.  If  you  do  not  see  exactly  the  same 
image, adjust the viewfinder tube. On the search tube you will find small 
screws, which can be used to adjust the viewfinder tube until the object 
can  be  seen  exactly  in  the  viewfinder  tube.  Then  you  have  aligned 
telescope and finder telescope parallel to  each  other.  If you encounter 
the viewfinder, repeat the procedure. 
The viewfinder should be set up before each observation. 
 

 

 
Aligning the telescope with a paralactic mounting 
Important  information:  We’re  trying  here  to  explain  to  you  the  alignment  of  a  paralactic  mounting  as  easily 
and  descriptively  as  possible.  But  you  should  still  bear  in  mind  that  difficulties  can  arise,  despite  the 
instructions. So please don’t be afraid to look for any additional help. Construction videos on the Internet are 
very helpful here, like the ones you can find on Youtube.  
You  have  to  align  the  telescope  so  that  you  can  find  the  celestial  objects  later.  Please  remember  that  the 
mounting, therefore the tube and the opening, points northwards. You can use a compass here.  

 

First  align  the  right  ascension  axis  (polar  axis),  with 
the help of a compass, northwards. That means that 
the telescope tube, with it’s opening, points towards 
the polar star.  
Now  look  through  the  finderscope  and  aim  at  the 
polar  star.  The  polar  star  should  be  visible  in  the 
middle of the visual field of the finderscope. 

 

Now adjust the correct latitude.  
You  can  adjust  the  latitude  with  the  altitude 
adjustment  T-bolt  on  the  lateral  latitude  scale.  You 
can find out the exact latitude of your location on the 
Internet.  
The  latitude  in  Germany  is  usually  about  50 
degrees. You’re adjusting the latitude by turning the 
altitude  adjustment  T-bolt.  The  telescope  tube  will 
then tilt in this angle.   

 

 

 

You can now trace the movement of the stars, if you found a celestial object, through the tracking of this right 
ascension axis. We want to explain this to you briefly: The celestial objects seem to move in a circular path, 
because  the  earth  rotates.  If  we  don’t  move  the  telescope  and  just  keep  looking  at  one  point,  then  the 
celestial object will be soon out of your visual field.  
But  if  you’ve  adjusted  and  aligned  the  telescope  correctly,  then  only  the  fine  adjustment  with  the  shafts  is 
necessary, so that you can observe the object, without it disappearing from your visual field.
