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.
RISK of bodily injury!
Never use this device to look directly at the
sun or in the direct proximity of the sun.
There is a RISK OF BLINDNESS!
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 finder-
scope be adjusted. The finderscope and main telescope
must have identical positioning.
HINT!
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.
i
The image is vertical but inverted. The image reproduction in
the viewfinder is neither perpendicular nor true to side. 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 cor-
responds to the view through the main telescope eyepiece.
Focusing the finderscope:
Turn the rear lens mount (Fig. 10, X) one to two turns to the
left.You can then set the counterring separately.
Look through the finderscope and focus on a distant object.
Turn the lens mount in one direction or the other until the
object appears sharpest.
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 ascen-
sion 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 clamp-
ing screw in the axis notch provided.
The short flexible shaft (illustration 1, 15) is mounted later-
ally. It is secured in place with a clamping screw in the axis
notch provided.
Your telescope is now ready for use.
Part II – Handling
1. Handling – telescope mount:
Your telescope mount is of a new type allowing you to make
two different types of observation.
A: Azimuth = ideal for terrestrial use.
B: Parallactic = ideal for celestial observation.
Re A.
In azimuth use the telescope is moved horizontally and vertically.
1. Undo the polar vertical clamping screw (illustration 14a,
X) and lower the incline plate until it is horizontal (to the
stop). Retighten the polar height fastening screw.
2. Undo the vertical clamp (illustration 15 A) and move the
main tube to a horizontal position. The re-tighten the clamps.
The telescope can now be moved horizontally and vertically
using the flexible shafts (illustration 1, 14+15).
Re B.
2. Handling. Night use.
A dark site is very important at night as light would interfere
with observation focus and detail visibility.
Allow your eyes to adjust to the darkness after leaving a
lighted room. After about 20 minutes you can begin celestial
observation.
Do not use the telescope from within enclosed spaces.
Position your telescope and accessories about 30 minutes
before observing to ensure temperature compensation in the
main tube. Make sure the telescope is on a flat stable surface.
3. Setup - alignment - basic siting.
Undo the polar height clamping screw (illustration 14a X)
and move the inclined plate (illustration 15 B) to the latitude
of your location using the holding rod table as a rough
guide. Turn the
tripod so that the N mark faces north. The top of the inclined
plate should also face north (illustration 14b). The latitude
setting rod (illustration 14a Y) points south.
4. Setting latitude.
Determine latitude of your location using a street map, atlas
or the Internet. Germany is between 54° (Flensburg) and
48° (Munich) degrees of latitude.
Undo the polar height adjustment clamping (illustration 14 X)
and set the angled plate until the figure on the latitude adjust-
ment rod (illustration 14 Y) is that of your location, e.g. 51°)
5. Turn the declination axis (illustration 15 C)
incl. telescope mount 90°.
Set the tube the right way round (see illustration / marking) in
the mounting and tighten the clamping screw. The telescope
eyepiece projection now points to the ground and the lens
to the polar star. Undo the latitude setting clamping and the
DEC axis in that sequence and get the polar star in the middle
of the eyepiece field of vision. Then re-tighten the clamping.
The tripod may not now be moved or adjusted again as this
would misalign it. The telescope is now correctly aligned. This
procedure is essential so that celestial objects are tracked.
6. Tracking and observation positioning
Tilt the main telescope (main tube) 90° (illustration 15 C).
Turn it 180° to the right or left until the objective lens shows
skywards.
Tighten all clamping (illustration 13 Y + illustration 15 A) so
that tracking can be done using the flexible shaft.
Manual use of the hours axis (R.A. axis) via the flexible
shaft (illustration 15 D) compensates for the earth‘s rotation
so that objects remain always in the eyepiece visual field.
If you want to move to another object undo the clamping
(illustration 13 Y + illustration 15 A), rotate the main tube
