remove fingerprints from the optical surfaces is with a lint free,
soft cloth, which you have previously treated with some alcohol.
Even better 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 interesting and easy-to-find celestial objects. On the
depending pictures 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 second-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
planetary 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 sur-
rounds 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.
