Part I – Construction
1. General/Location:
These instructions detail the assembly and use of refracting and
reflecting telescopes with equatorial mountings (also called
German mountings).
Parts of these instructions hence contain differing instructions for
the differing telescope models.
Before you begin construction, you must choose a suitable
location for your telescope.
It will help you, if you build this appliance in a place, where you
have a clear view of the skies, a stable footing and sufficient
space around you.
Remove all the parts from the packaging first. Check, using the
diagram, whether all the parts are there.
Important: Only do the screws up finger tight and avoid over
tightening them.
2. Tripod
The tripod legs are pre-installed and already connected to the
tripod head (illustration 5, X) and tripod spider (illustration 1, 16).
Remove the tripod from it's packaging and place it upright with
the feet at the base. Take two of the legs and carefully pull them
apart until they are in the fully open position. The entire weight of
the tripod rests on one leg during this procedure. Then set the
tripod upright again.
Now extend each individual tripod leg to the desired length (see
illustration 4) and then tighten the clamping screw on each
(illustration 4, 11) (a total of 3) until they are all hand tight. Do
not overtighten them. The clamping screws serve to set the
tripod leg interior segments to the desired height.

HINT:
A small spirit level, placed on the accessory tray, may
help you to setup you telescope in level.
3. Mounting
Next the mounting (illustration 1, 9) is fastened to the tripod head
(illustration 5, X). To do so insert the mounting from above in the
tripod head and turn the knurled screw hand tight from below.
First prepare the mount (Fig. 1, 9), put the weight on the weight
shaft pole (Fig. 7, X) and then screw it securely into the mount
from below.
The tube ring (Fig. 1+3, 8) should now be placed on the mount
and fixed with the screw (Fig. 8, X).
4. Accessory tray:
The accessories tray (illustrations 1, 3, and 10) is inserted with
the flat side down centrally on the tripod spider (illustration 1, 16)
and mounted in place by turning clockwise once (60°) (illustration
6). The three fittings of the accessories tray must be aligned
with the tripod spider retaining fittings and fixed in place by
them.
5. Tube:
To mount the telescope tube (Fig. 1, 1) you undo the screw on
the tube ring (Fig. 9, X) and open up the ring.
Now you place the tube in the centre of ring and close the ring
up. Now secure the mounting by tightening the screw.
6. Inserting the eyepiece
6.1. Main accessories
One eyepiece (Fig. 2, 18) and a star diagonal prism (Fig. 2, 19)
are supplied as standard with this telescope.
Before you insert the eyepiece and the star diagonal prism, you
must remove the dust-protection-cap from the eyepiece
connection tube (Fig. 1, 6).
Loosen the screw (Fig. 12, X) on the eyepiece connection tube
and insert the star diagonal prism. Retighten the screw (Fig. 12,
X) on the eyepiece connection tube.
Then open and close the clamping screw (ill. 13a, X) to fasten
the 25 mm eyepiece in the zenith mirror in the same way.
Make sure that the eyepiece is pointing vertically upwards.
Otherwise loosen the screw (Fig. 12, X) on the eyepiece
connection tube and rotate the star diagonal prism into the
vertical position.
7. Assembling the finder scope
7.1. Finder scope installation
Finder scope and finder scope mounting (fig. 1a, 2) are included
in the packaging.
Undo the fastening screws of the finder scope mounting on the
main tube (fig. 1a, X) and set it on the projecting screws on the
telescope main tube. Then carefully reinsert the screws previous-
ly removed. The finder scope mounting is now securely fastened
in place.
Now undo the finder scope adjusting screws (fig. 1a, 3) – 3 or 6
of them depending on finder scope model - until the finder
scope can easily be slid into its mounting.
Important: Make sure the finder scope lens points toward the
main tube end (fig. 1, 4).
The 3 or 6 screws are then to be equally tightened until the
finder scope is securely fastened in place.
8. Aligning the finder scope
8.1 Aligning the finder scope
The finder scope must be adjusted before use. This means the
finder scope and the telescope main tube must be aligned
parallel to one another.
