Part I - The Structure

1. General information about the structure and the choice of location

Before you begin the assembly, you must choose a suitable location for your 

telescope. It helps, if you set up this instrument in a location where a clear view 

of the skies , a stable footing and sufficient space around you are given.

First, remove all the parts from the packaging. Using the diagram, check whether 

all the parts are included.

ATTENTION!

Only tighten the screws  with care  "hand-tight" to avoid "over-

tightening" the screws. This can cause damage to the  screws and 

threads

2. Set up the tripod

The tripod legs are pre-assembled and already connected to the tripod head (Fig 

5, X) and the tripod spider (Fig 1, 16).

Remove the tripod from its packaging and place it vertically with the tripod feet 

facing down. Now take two of the tripod legs and carefully pull these tripod legs 

apart to the fully open position. The entire weight of the tripod rests on one leg. 

Then set up the tripod straight.

Now pull out each tripod leg individually to the desired length (Fig 4) and now 

turn one each of the clamping screws  (Fig 4, 11)  3 pieces      hand-tight. Do not 

overtighten the screws! The clamping screws are used to lock the inner tripod leg 

segments at the desired height.

TIP:

A small spirit level on the accessory tray can help you set up your 

tripod level.

i

3. Insert mount

Next, attach the mount (Fig 1, 9) to the tripod head (Fig 5, X). To do this, insert 

the mount in to the top of the tripod head and hand-tighten the thumbscrew 

from below.
The mount (Fig 1, 9) is assembled by sliding the weight on to the weight rod (Fig 

7, X) and screwing it firmly in to the thread of the mount from below.
The mount is completed by placing the tube clamp (Fig 1+3, 8) on the mount and 

securing it with the screw (Fig 8, X).
Maksutov optics do not have a tube clamp. The rail is placed directly on to the 

mount.

4. Mount shelf

The accessory tray (10) is mounted to the mounting struts with the beveled sides 

facing down. To do this, the screws (Fig 6, X) are pushed through the holes in the 

tray and the brackets from above and screwed on with the wing nuts (Fig 6, Y) 

from below.
