ASSEMBLY

Fig. 1d). Note that there is a triangular pointer above the scale on the
mount. The pointer is not fixed. It moves as soon as the mount moves.
Determine the latitude of your observation location. You can find informa-
tion on this in our additional literature (download via link on p. 2) or take
a look at the atlas. Loosen the clamp for the polar height ( Fig. 1d, 25)
and turn the polar height adjustment screw ( Fig. 1d, 27) until the pointer
shows the latitude you want. The adjustment screws work by an adjust-
ment and counter mechanism (i.e. before you tighten one, loosen the
other). Once the pointer shows the latitude you want, tighten both screws
until they have contact with the mount.

7. Attaching the prism railto the mount (bracket): Remove the tube from the

tube clamp and slide the tube clamps connected withe prism rail (11, Fig.
1a) into the prism holder (see Fig. 7). The dovetail base of the rail fits into
the prism holder of the mount (A, Fig. 7). Tighten the prism locking screw
(B, Fig. 7) good on. Insert the tube into the clamps and hand-tighten the
tube clamping screws.

8. Positioning of the tube in the tube clamp: Hold the tube firmly, open the

tube clamping screws (13, Fig. 1a) and slightly loosen the tube clamp.
While you are holding the tube (10, Fig. 1a) firmly, position it between
the tube clamps so that the centre of the tube is approximately in the
middle of the tube clamps. Depending on the design, align the tube so
that the front side (9, Fig. 1a at the N) looks as shown on the title page.
Then close the tube clamps (13, Fig. 1a) above the tube again. Tighten
the screws so that they hold the tube, but you are still able to balance
/ to move it. For more information, see "

page 10.

9. Attaching the viewfinder (Fig. 9): The viewfinder is already included in the

package with pre-mounted bracket. Remove the thumbscrews from the
optical tube and set aside. Place the viewfinder bracket on the two set
screws and screw the thumbscrews back on.

10. Inserting the eyepiece (Fig. 10): First remove the dust cap from the

eyepiece holder on the focusing unit. Place the dust cap in a safe
place and replace it when you have finished observing to prevent dirt
from entering the telescope. Open the eyepiece clamping screws (1,
Fig. 1a) and insert the supplied eyepiece (3, Fig.1a) into the eyepiece
holder. Then hand-tighten the screws to prevent the eyepiece from
slipping out.

11. Adjusting the tripod height: Adjust the tripod by loosening the locking

screws (38, Fig. 1c) on the tripod. Then pull the inner tripod legs to the
desired length. Then tighten the screws again. Adjust the tripod to a
height that makes observing as comfortable as possible.

Getting Started

Balancing the telescope

To ensure that the telescope is secure and stable on the tripod and moves
smoothly and evenly, it must be balanced. To balance the telescope, open
the RA clamp (33, Fig. 1d). When the axis is free, the telescope rotates
around the RA axis. Later on, you will also have to open the DEC clamp
(17, Fig. 1d). When is opened, the telescope will also rotate around the
DEC axis. The movement of the telescope occurs around these two axes,
individually or simultaneously. Try to familiarize yourself with these clamps
and observe how the telescope is moving around each axis. To find the
best possible balance for your telescope, follow the method described
below:

1. Hold the tube tightly so that it does not swing around freely by accident.

Loosen the RA clamp (33, Fig. 1d). The tube now moves freely around
the RA axis. Now let the telescope rotate until the counterweight rod is
parallel to the ground.
