appropriately and then re-tighten the clamping. Fine adjust-

ment is done using the flexible shaft (illustration 1 14+15).

HINT!

The latitude of your observation site can be

found in maps or in the internet. A good sour-

ce 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 eye-

piece and the viewfinder into a position in which is comfort-

able 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

middle 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)

picture 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 posi-

tion in the heavens will change. The pole star is the excep-

tion. 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

reversal (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 nor-

mal magnification 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 attachmentIn 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 magni-

fication. The image appears out of focus. This is

not a defect but due to technical 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

astronomical observations. Only use the dia-

gonal mirror here. To observe landscapes,

you may use the erecting lens.
