Part I – Setup
1. General/Location:
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. Setup - 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.
The entire tripod weights rests on one leg here. Then set the
tripod upright again. Now extend each individual tripod leg to the
desired length (see illustration 4) and undo the fastening clips for
this purpose (illustration 1+4, 11) (total of 3). Tighten the fastening
clips and place the tripod on a hard flat surface.
3. Setup – accessory tray:
Three 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
5). The three fittings of the accessories tray must be aligned with
the tripod spider retaining fittings and fixed in place by them.
4. Setup – tube:
To mount the telescope tube (Fig. 1, 1) you undo the screw on the
tube ring (Fig. 6, X) and open up the ring.
Now you place the tube in the centre of ring and close the ring up.
HINT:
A small spirit level, placed on the accessory tray, may
help you to setup you telescope in level.
Now secure the mounting by tightening the screw.
Place the tube including clip with the objective opening facing
north on the mounting. Fasten the tube holder using the clamping
screw to the mount head (illustration 7).
5. Setup – eyepiece:
Two eyepieces (Fig. 1+2, 18) and a star diagonal prism (Fig. 1+2,
19) are supplied as standard with this telescope.
With the eyepieces, you can decide which magnification you want
for your 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. 8, X) on the eyepiece connection tube and
insert the star diagonal prism. Retighten the screw (Fig. 8, X) on
the eyepiece connection tube.
Repeat the same process on the star diagonal screw (Fig. 9, X)
and insert 20mm eyepiece in the star diagonal prism and
retighted.
Make sure that the eyepiece is pointing vertically upwards.
Otherwise loosen the screw (Fig. 8, X) on the eyepiece connection
tube and rotate the star diagonal prism into the vertical position.
6. Setup – viewfinder assembly and alignment
The view finder and its holding device are pre-assembled and
included in the packaging
Push the foot of the viewfinder holding device completely into the
telescope barrel base (illustration 10). The holding device will click
into place. Make sure that the viewfinder lens faces the barrel
opening.
There are two clamping screws (black) on the holding device
(illustration 1, 3) plus a spring-loaded counter screw (silver). The
black clamping screws are now to be screwed in until resistance
is felt. This affixes the viewfinder barrel in place.
Before you start any observation it is essential the finderscope be
adjusted. The finderscope and main telescope must have
identical positioning.
To align them proceed as follows:
take the 20 mm eyepiece, insert it in the zenith mirror and align the
main telescope with an easily found and identified earthly object
such (illustration 11, church tower top, house gable). The distance
should be at least 200m – 300m meters. Place the object dead
centre of the eyepiece vision field. The image is vertical but
inverted. The finderscope image is vertical and correctly shown.
Turn (right/left) one of the two finderscope adjustment screws
whilst looking through the finderscope. Continue until the
finderscope hairlines are at exactly the position that corresponds
to the view through the main telescope eyepiece.
Focussing the finderscope:
turn the front lens barrel (illustration 10, X) left one or two turns.
You can then set the counterring separately. Look through the
finderscope and focus on a distant object. Turn the front lens
barrel part either way until the focus is good. Now turn the
counterring toward the lens barrel.
7. Setup – protection-caps:
In order to protect the inside of your telescope from dust and filth,
the tube opening is protected by a dust-protection-cap (Fig. 12,
X). For observation remove the cap from the opening.
8. Setup - flexible shafts
To ease precise adjustment of the declination and right
ascension axes flexible shafts are installed in the holding devices
of both axes provided for the purpose (illustration 13, X).
The long flexible shaft is mounted parallel to the telescope barrel
(illustration 1, 14). It is secured in place with a clamping screw in
the axis notch provided.
The short flexible shaft (illustration 1, 15) is mounted laterally. It is
