ter is the use of compressed air from a can. If your telescope has

collected dust or moisture internally, do not try to clean it yourself

but return it directly to your local specialist.

Don’t clean the telescope’s optics too often. Doing this, may

result in damaged coatings. If you telescope should have become

dusty from the inside, don’t attempt to clean it on your own but

consult your local dealer or BRESSER centre of your country.

Appendix

1. Possible observation targets

In the following, we like to present to you a choice of very inter-

esting and easy-to-find celestial objects. On the depending pic-

tures at the end of the manual you will see how they will appear

in the eyepiece of your telescope:

The moon (Fig. 21)

The moon is the only natural satellite of the earth.

Diameter: 3,476 km

Distance: 384.000 km (average)

The moon is well-known since thousands of years. He is the sec-

ond-brightest celestial object after the sun. Because the moon

circles around the earth, he changes periodically its inclination

to the sun; therefore we see changing phases. The time for one

complete lunation is 29.5 days (709 hours).

Constellation Orion: The great Orion nebula / M 42 (Fig. 22)

Right Ascension: 05h 33’ (hours : minutes)

Declination: -05° 25’ (Degrees : minutes)

Distance: 1.500 light years

Though it is 1,500 light years away, the Orion nebula (M 42) is

the brightest nebula object at the sky – visible even with naked

eyes and a worthwhile object for telescopes of all kinds and

sizes. It consists of a gigantic cloud of hydrogen gas with a diam-

eter of hundreds of light years, taking a field on the sky of 10°.

Constellation Lyra: The Ring Nebula / M 57 (Fig. 23)

Right Ascension: 18h 52’

Declination: +32° 58’

Distance: 4.100 light years

The famous Ring Nebula is often called the prototype of plan-

etary nebulae; he belongs to the northern hemisphere summer

sky’s pieces of splendour. Recent investigations have shown that

he is a ring of light-emitting matter that surrounds its central star

(only visible in bigger telescopes). If one could look onto its top,

he would see a structure like the Dumbbell Nebular / M 27.

Constellation Vulpecula (little fox):

The Dumbbell Nebula / M 27 (Fig. 24)

Right Ascension: 19h 59’

Declination: +22° 43’

Distance: 1.250 light years

The Dumbbell Nebula / M 27 was the first planetary nebula ever

found. On July 12th, 1764, Charles Messier discovered this new

and fascinating class of objects. We can see it directly from its

equatorial pane. If it could be viewed from top, we would appear

like the Ring Nebula / M 57. This Object can even be viewed at

average weather conditions at low magnifications.

3. Troubleshooting:

Mistakes: Help:

No picture Remove dust protection cap and

sunbathe-shield from the objective

opening.

Blurred picture Adjust focus using focus ring

No focus possible Wait for temperature to balance out

Bad picture Never observe through a glass

surface

Viewing object visible Adjust finder (See Part I:

in the finder, but not 6. Construction)
