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.
NOTE!
i
The right ascension axis (green line, illustration
16) is also called the axis of sidereal time on
the meridian. The declination axis (blue line,
illustration 16) is also called the elevation axis.
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.
Note: The main tube clamp may have 2 screws depending on
model (ill. 9b). Mounting the main tube is in principle
as given here.
6. Inserting the eyepiece
6.1. On refracting telescopes
Two eyepieces (Fig. 2, 18) and a star diagonal prism (Fig. 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. 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 20 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.
6.2. On reflecting telescopes
Please loosen the clamping screw on the eyepiece supports (fig.
1, 6). Remove the eyepiece supplied (fig. 2,18) with the 20 mm
maximum focal length and insert it directly in the eyepiece sup-
ports. Hand tighten the clamping screws (fig. 3b, X). Remove the
dust cap from the main tube end.
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!
7. Assembling the finder scope/LED finder scope
Note: The LED finder scope has a battery safeguarded
against discharge with plastic foil when shipped. This
must be removed before first use (fig.1d).
7.1. Finder scope installation (type I). Finder scope with
threaded mounting
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 fin-
der scope is securely fastened in place.
7.2. Finder scope assembly (type II) LED finder scope with
screw threading
To assemble the LED finder scope (fig 1b, 2) first remove the
fastening screws for the LED finder scope on the telescope main
tube (fig. 1c, X). Now set the LED finder scope on the projecting
screws on the telescope main tube. Then carefully reinsert the
screws previously removed.
Important. Make sure the LED finder scope lens points towards
the main tube end (fig. 1, 4).
7.3. Finder scope assembly (type III) LED finder scope with
Quick Insert
The LED finder scope (fig. 1b, 2) and mounting constitute a sin-
gle unit. Slide the foot of the LED finder scope completely into
the appropriate base on the telescope main tube (fig. 10, X). The
finder scope mounting will snap in place.
Important. Make sure the LED finder scope lens points towards
the main tube end (fig. 1, 4).
7.4. Finder scope assembly (type IV) Finder scope with Quick
Insert
The finder scope and its mounting are pre-assembled and inclu-
ded in the packaging.
Slide the finder scope mounting foot entirely into the appropriate
base on the telescope main tube (fig. 10, X). The finder scope
mounting will snap in place.
Important. Make sure the LED finder scope lens points towards
the main tube end (fig. 1, 4).
There are two clamping screws (fig. 1c, 3) and a spring-loaded
counter screw on the finder scope mounting. The clamping
screws are now to be evenly screwed in until resistance is felt.
This affixes the finder scope in place.
8. Aligning the finder scope
8.1 Aligning types I + IV (finder scopes)
The finder scope must be adjusted before use. This means the
finder scope and the telescope main tube must be aligned paral-
lel to one another.
Insert the eyepiece with the greatest focal length in the zenith
mirror (13a, refracting telescopes only) or directly in the eye-
piece supports (fig. 13b, reflecting telescopes only). Point the
telescope at a significant object approximately 300 meters away
(e.g. house gable, church tower top, etc.) and adjust until it
appears in the centre of the field of vision (ill. 15, A).
