HINT!

The latitude of your observation site can be

found in maps or in the internet. A good source

of information is www.heavens-above.com. After

checking “anonymous user” > “select” you may

choose your land and city.

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. Handling – Viewfinder:

The telescope is now roughly aligned and adjusted.

In order to obtain a comfortable observation position, you

should loosen the screws at the tube mounting (Fig. 1, 8), so

that you can rotate the telescope tube. Bring the eyepiece and

the viewfinder into a position in which is comfortable for you to

look through both.

The fine alignment is done by using the finder scope. Look

through the finder scope and centre Polaris (Fig. 16) in the mid-

dle of the finder scope (Fig. 17).

For fine adjustments use the flexible handles of the horary axis

(Fig. 15, D) and of the declination axis (Fig. 15, E).

8. Handling - Observation:

After you have located the pole star in the viewfinder, if you look

through the eyepiece, the pole star will be visible.

If necessary, you can with help of the flexible handles align the

star more exactly, just as you can adjust the definition by using

the focussing wheel (Fig. 15, F).

Furthermore, you can now, by changing the eyepiece, increase

the magnification. Note that the magnification of the stars can

hardly be seen.

HINT!

Eyepieces enlarge the (not directly visible) pic-

ture of the telescope’s prime focus. The less the

eyepiece’s focal lengths is, the stronger is the

magnification. So various eyepieces are needed

to reach different magnifications. Begin every

observation with a low magnification (20mm

eyepiece).

9. Handling – Find a star:

Initially it will be difficult for you to find your bearings in the

firmament, since the stars and the constellations are always

moving and according to season, date and time their position in

the heavens will change. The pole star is the exception. It is a

fixed star and the starting point for all star maps.

At the beginning, you should look at some well known

constellations and star groups order that are visible the whole

year over. The position of the heavenly bodies is however

dependent on date and time.

If you have aligned your telescope accurately on one of these

stars, you will find that it has vanished your visual field after a few

minutes. To even out this effect, you must turn the

flexible handle (Fig. 15, D) the horary axis and your telescope

will follow the trajectory of this star.

10. Handling – Accessories:

Your telescope is equipped with two eyepieces (Fig. 2, 18) as

part of the basic equipment. By interchanging the eye pieces you

can alter the magnification of your telescope.

The star diagonal prism (Fig. 2+18, 19) causes a picture rever-

sal (mirror wrong) and is put into the telescope before viewing

the earth.

In order to see an upright and sidecorrect picture, you may

use the erecting lens. Loosen the locking screw (Fig. 8, X) and

remove the diagonal mirror from the eyepiece holder (Fig. 1, 6).

Now put the erecting lens (Fig. 2, 20) in place and retighten the

locking screw (Fig. 19). At last, put an eyepiece (e.g. f=20mm)

in place and tighten the locking screw (Fig. 9, X).

In order to increase the magnification, you can also use the

Barlow lens (Fig. 2, 21) instead of the inverted eyepiece (Fig. 2,

20), as described above (Fig. 19b). Thus, the normal magnifica-

tion can be increased by three times. Use of the Barlow lens

together with the star diagonal (Fig. 18b) is recommended for

terrestrial observations.

HINT!

The indicated maximum magnification for this

telescope is calculated from the following formu-

la: Telescope focal length: Eyepiece focal length

x magnification of the attachment

In order to detect objects at this magnification,

the conditions of the natural surroundings must

be right. Since this is seldom the case, a sharp

enough image cannot normally be achieved with

the maximum magnification. The image appears

out of focus. This is not a defect but due to tech-

nical reasons.

11. Smartphone Holder:

When making the assembly, use the parts in the order as shown

in Fig. 20. Tighten the thread firmly. Launch your smartphone

SkyApp. Align the Smartphone parallel to the tube.

RISK of material damage!

Make sure to fix the clamps well while installing the holder, to

avoid dropping your smartphone.

The BRESSER GmbH assumes no liability for damages caused

by mishandling the device itself or to alternative devices (optics,

smart phones, etc.).

12. Handling – Dismantling:

After a hopefully interesting and successful observation, it is

recommended that you store the entire telescope in a dry, well

aired area. On some telescopes the tripod and mount can easily

be separated. The adjustments to the mount will remain intact.

Don‘t forget to put the dust-protection-caps onto the tube

opening and onto the eyepiece connection. Also, you should

stow all the eyepieces and optical accessories into their

corresponding receptacles.

HINT!

The erecting lens is not recommended for astro-

nomical observations. Only use the diagonal

mirror here. To observe landscapes, you may

use the erecting lens.

NOTES on cleaning

Your telescope is a high-quality optical appliance. Therefore you

should avoid your telescope coming into contact with dust or

moisture. Avoid putting fingerprints on the lens.

If dirt or dust have nevertheless accumulated on your telescope,

you should first remove it with a soft brush. Then clean the

soiled area with a soft, lint-free cloth. The best way to remove

fingerprints from the optical surfaces is with a lint free, soft cloth,

which you have previously treated with some alcohol. Even bet-
