IMPORTANT NOTE! Always make sure, that the base of your telescope is fixed to the 

TEPP, and it cannot fall off! Manufacturer doesn’t take any responsibility if your 

telescope is fall off of the TEPP because of a non appropriate mounting! 

 

If you cannot use the center point of the base for 
mounting, use cable ties right next to the rubber 
legs of the upper part of the platform. This makes 
your setup stable enough not to fall off, even in a 
windy weather. 

 
 
 
 
 
 
 

 
 
 
The last step is to place 
your telescope and the 
accessories  onto  the 
base, 

and  keep  the 

center  of  gravity  as  low 
as  possible!  In  order  to 
do  that,  you  may  use 
extra weights at the main 
mirror 

side 

of 

the 

telescope. 

This 

way 

you’ll  be  able to  achieve 
more accurate guiding

 

 

 

 

 

2.3 Precision Polar Alignment 

To get more precise polar aligment you can follow the steps of the Scheiner method. A detailed 
description can be found on the webpage below (note: for this method, you have to start the 
platform first):

2.4 Finding the Target Object 

Since TEPP is already operating in clock-machine mode (TEPP is turned on), as a first step, 
manually set up the direction with the help of the finder scope, or with a lasepointer. Now you 
can  calibrate  and  finetune  the  position  with  the  remote  controller,  untill  the  target  is  in  the 
middle of the frame. It is recommended to doublecheck the position through the ocular first, 
then setting up the camera itself. After repeated recalibration of the frame (putting the target 
into the very middle of the frame), you can start the calibration of tracking. With some practice, 
this all setup takes less than 10 minutes, so you will have 100 minutes to take pictures before 
TEPP stops.
