3. Accessory Tray
The accessory tray (No. 1 and 3, 10) should be attached to the center of the
tripod brace (No. 1, 16) with the flat side down. The center hole in the tray
should be fitted over the tripod brace retaining fittings. Mount the tray in place
by turning it clockwise 60° (No. 5).
4. Telescope Tube
To mount the telescope tube (No. 1, 1) you undo the screw (No. 6, X) on the
tube ring (No. 1 and 2, 8) 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. Position the tube, including the ring, with the objective opening facing
north, and place it on the tripod head (No. 1, 9). Fasten the tube to the tripod
head using the clamping screw (No. 7, X).
5. Eyepieces
Three eyepieces (No. 1 and 2, 18) and a diagonal mirror (No. 1 and 2, 19) are
supplied with this telescope. The three eyepieces allow you to decide which
magnification you want for your telescope. Before you insert the eyepiece and
the diagonal mirror, you must remove the dust protection cap from the eyepiece
connection tube (No. 1, 6). Loosen the screw (No. 8, X) on the eyepiece connec-
tion tube and insert the diagonal mirror. Retighten the screw (No. 8, X) on the
eyepiece connection tube.
Repeat the same process on the diagonal mirror screw (No. 9, X) and insert 20
mm eyepiece in the diagonal mirror and retighten.
Make sure that the eyepiece is pointing vertically upward. If it is not, loosen the
screw (No. 8, X) on the eyepiece connection tube and rotate the diagonal mirror
into the vertical position.
Risk of blindness
Never use this device to look directly at the sun or in the
direct proximity of the sun. Doing so may result in a risk of
blindness.
6. Viewfinder Assembly and Alignment
The viewfinder scope (No. 1 and 2, 2) and its holding device are preassembled.
Push the foot of the viewfinder scope holding device completely into the base
on the telescope tube (No. 10). The holding device will click into place. Make
sure that the viewfinder scope lens (No. 10, X) faces the barrel opening (No.
1, 4).
There are two black clamping screws on the holding device (No. 1, 3) plus a
silver spring-loaded counter screw. Tighten the black clamping screws until you
feel resistance. This affixes the viewfinder scope barrel in place.
Before you start any observation, it is essential to adjust the viewfinder scope.
The viewfinder scope and main telescope must be positioned identically in
order to make observations with your telescope.
HINT
Insert the 20 mm eyepiece in the diagonal mirror and align
the main telescope with an easily identifiable terrestrial
object (No. 11, A). The object should be at least 200–300
metres away. Position the telescope so that the object
appears in the center of the eyepiece's field of vision. The
image should appear vertical but inverted.
i
Follow the hint above. Once the telescope is aligned, look through the viewfind-
er scope. The image should be vertical and not inverted. To align the viewfinder
scope, turn one of the two adjustment screws (No. 1, 3) until the image appears
exactly the way it does through the telescope's eyepiece (No. 11, B).
To focus the viewfinder scope, turn the viewfinder's front lens barrel (No. 10, X)
left or right until the picture appears sharp and clear.
7. Protection Caps
In order to protect the inside of your telescope from dust and dirt, the barrel
opening (No. 1 and 12, 4) is protected by a dust protection cap (No. 12, X).
Before you begin observing with your telescope, remove the cap from the
opening.
8. Flexible Shafts
To ease precise adjustment of the declination and right ascension axes, install
the flexible shafts (No. 1 and 3, 14 and 15) in the holding devices of both axes
provided for the purpose (No. 13, X and Y).
The long flexible shaft should be mounted parallel to the telescope barrel (No.
1, 14). Secure it in place with the provided clamping screw in the axis notch. The
short flexible shaft (No. 1, 15) should be mounted laterally. Secure it in place
with the provided clamping screw in the axis notch.
Your telescope is now ready for use.
Part II—Handling
Telescope Mount
Your telescope mount is of a new type that allows you to make two different
types of observations:
A. Azimuth, ideal for terrestrial use
B. Parallactic, ideal for celestial observation
A. In azimuth use:
The telescope is moved horizontally and vertically.
1. Undo the polar vertical clamping screw (No. 14a, X) and lower the incline
plate (No. 1, 17; No. 15, B) until it is horizontal (all the way to the stop).
Retighten the polar vertical clamping screw.
2. Undo the vertical clamp (No. 15, A) and move the telescope until it horizontal.
Then retighten the vertical clamp. The telescope can now be moved horizontally
and vertically using the flexible shafts (No. 1, 14 and 15; No. 14, D and E).
B. In parallactic use:
2. Night Use
A dark site is very important for observation at night as light interferes 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 within an enclosed space. Position your telescope
and accessories in place outside about 30 minutes before observing to ensure
temperature compensation in the telescope tube. Make sure the telescope is
on a flat, stable surface.
3. Alignment—Basic Siting
Undo the polar vertical clamping screw (No. 14a X) and move the incline plate
(No. 1, 17; No. 15, B) to the latitude of your location using the latitude adjust-
ment rod as a rough guide. Turn the tripod so that the N mark faces north. The
top of the incline plate should also face north (No. 14b). The latitude adjust-
ment rod (No. 14a, Y) should point south.
4. Setting Latitude
Determine the 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 vertical clamping screw (No. 14a, X) and move the incline plate
(No. 1, 17; No. 15, B) until the number on the latitude adjustment rod (No. 14a,
Y) matches that of your location.
5. Final Alignment
Turn the declination axis (No. 15, C), including the telescope, 90°.
Place the tube with the correct orientation into the holder and tighten the clamp-
ing screw. The telescope eyepiece should now point to the ground, and the lens
should point to the sky. Undo the polar vertical clamping screw and the declina-
tion axis in that order, and position the telescope so that the polar star appears
in the center of the eyepiece's field of vision (No. 17). Then retighten the polar
vertical clamping screw and the declination axis.
