5. Tube
Now hold the telescope main tube (1) as shown in the middle of the
alt-azimuth mount (9) and screw the screws (8) into the tube from both
sides (Fig. 8).
6. Vertical fine adjustment
To mount the vertical fine adjustment (17) first push the adjustment rod
through holding device (X) on the mount (Fig. 9a).
Then undo the screw (Y) for the adjustment rod and insert on the other
end of the rod. Then tighten it in place (Fig. 9b).
Important: Do not screw the vertical fine adjustment fastening
screw too tightly. If you do the main tube will not be
vertically adjustable.
RISK OF BLINDNESS!
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, 14) and set it on the projecting screws on the telescope
main tube. Then carefully reinsert the screws previously 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.
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,
14). 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 single 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 included 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, 14) 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 parallel to one
another.
Insert the eyepiece with the greatest focal length in the zenith mirror
(12b, refracting telescopes only) or directly in the eyepiece supports
(fig. 13, 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
(Fig. 15a, A).
Look through the finder scope and align it by turning the 3 or 6
adjustment screws until the object is visible in the middle of the
crosshairs. The image you previously saw through your telescope
lens must now be visible exactly in the centre of the finder scope (2)
crosshairs too (Fig. 15a,C).
HINT:
i
Some finder scopes have no integrated optical image
reversion. The image in the finder scope is then upside
down. This is not a fault.
8.2 Alignment, types II + III (LED finder scopes)
The LED finder scope must be adjusted before use. This means that the
LED finder scope and the telescope tube must be aligned in parallel.
Insert the eyepiece with the greatest focal length in the zenith mir-
ror (Fig. 12b, refracting telescopes only) or directly in the eyepiece
supports (Fig. 13, 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 (Fig. 15b, A).
Then turn the LED finder scope (2) on using the On/Off switch (Fig. 1b,
Z). Select setting „2" in daylight, setting „1" for nighttime.
Look through the LED finder scope and align it by turning the horizontal
(Fig. 1b, X) and vertical (Fig. 1b, Y) adjustment screws until you see
the red dot in the centre of the image (Fig. 15b, C). Finder scope and
telescope are now adjusted to one another.
9. 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. 11, X).
For observation remove the cap from the opening.
10. Inserting the eyepiece
10.1. On refracting telescopes
Two eyepieces (18) and a star diagonal prism (19) are supplied as stan-
dard 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 (6).
Loosen the screw (Fig. 12a, X) on the eyepiece connection tube and
insert the star diagonal prism. Retighten the screw (X) on the eyepiece
connection tube.
Then open and close the clamping screw (Fig. 12b, 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. 12a, X) on the eyepiece connection tube and
rotate the star diagonal prism into the vertical position. Remove the dust
cap from the main tube end.
10.2. On reflecting telescopes
Please loosen the clamping screw on the eyepiece supports (6).
Remove the eyepiece supplied (18) with the 20 mm maximum focal
length and insert it directly in the eyepiece supports. Hand tighten the
clamping screws (Fig. 13, X). Remove the dust cap from the main tube
end.
