TIP:

Eyepieces are lens systems designed for your

eye. In an eyepiece, the clear image that is ge-

nerated in the focal point of a lens is captured

(in other words, made visible) and magnied

still more. Eyepieces with various focal widths

are necessary in order to achieve various de-

grees of magnication. Begin each observati-

on with an eyepiece with a low magnication

(= large focal width, e.g. 20 mm).

The telescope is now properly oriented. This

procedure is necessary for tracking celestial

bodies.

6. Tracking- and/or Observation Position

Loosen the vertical clamp (8) and tilt the te-

lescope tube 90° downwards. Loosen the

horizontal clamp (33) and turn the telescope

180° to the right or left, until the objective

lens is pointing in the direction of the sky.

Retighten all clamps so that you can track

with the exible shaft.

The manual operation of the counterweight

axis (right ascension axis, R.A. axis) via the

exible shaft (26) allows for the rotation of the

Earth in such a way that the positioned object

always stays in the eyepiece eld of vision.

If you would like to switch to another object,

loosen the clamps, swing with the tube in the

proposed direction and retighten the clamps.

The ne adjustment is then performed with

the exible shafts (14, 15) (Figures 1).

7. Finder

Your telescope is now roughly aligned and set

up.

In order to obtain a comfortable observation

position, carefully loosen the screw on the

tube clamp (8) (Figure 1) so that you can turn

the telescope tube. Bring the eyepiece and

the nderscope into a position from which

you can observe comfortably.

The ne adjustment happens with the help of

the nderscope (2). Look through the nder

and try to hone in on, for instance, the North

Star (Figure 16), positioning it in the middle of

the nder‘s crosshairs (Figure 17). For the ex-

act adjustment, the shaft of the counterweight

axis (26) as well as the shaft of the declination

axis (27) will be helpful.

8. Observation

After you have located the North Star in the

nder, you will be able to recognize the North

Star when you look through the eyepiece of

the telescope. If needed, you can angle the

telescope even more exactly toward the star

(with the help of the exible shafts), or you

can adjust the focus with the focus knob (7)

(Figure 1).

Additionally, you can now switch to a higher

magnication by changing the eyepiece (to a

smaller focal width). Please be aware that the

magnication of the stars is barely perceptib-

le.
