The moon has been known since prehistoric times. It is the second brightest
object in the sky after the sun. As the moon orbits the earth once a month, the
angle between the earth, the moon and the sun is constantly changing; you can
see this in the cycles of the moon's phases. The time between two consecutive
new moon phases is about 29.5 days (709 hours).
Constellation ORION / M42 (Fig 31)
Right Ascension (R.A): 05:32.9 (hours : minutes)
Declination (DEC):
05:25 (degrees : minutes)
Distance: 1.500 million light years
At a distance of about 1600 light-years, the Orion Nebula (M42) is the brightest
diffuse nebula in the sky - visible to the naked eye, and a rewarding object for
telescopes of all sizes, from the smallest binoculars to the largest Earth-based
observatories and the Hubble Space Telescope.
It is the main part of a much larger cloud of hydrogen gas and dust, extending
at more than 10 degrees over well over half of the constellation of Orion. The
extent of this enormous cloud is several hundred light years.
Constellation LEIER / M57 (Fig 32)
Right ascension:
18:51.7 (hours : minutes)
Declination (DEC):
32:58 (degrees : minutes)
Distance: 4.100 million light years
The famous Ring Nebula M57 in the constellation Lyra is often considered to be the
prototype of a planetary nebula; it is one of the splendours of the northern hemis-
phere summer sky. Recent studies have shown that it is most likely a ring (torus) of
brightly glowing matter surrounding the central star (visible only with larger tele-
scopes), rather than a spherical or ellipsoidal gas structure. If the Ring Nebula were
viewed from the side plane, it would resemble the Dumbell Nebula M27. We are
looking right at the pole of the nebula for this object.
Constellation Vixen / M27 (Fig 33)
Right Ascension (R.A): 19:59.6 (hours : minutes)
Declination (DEC):
22:43 (degrees : minutes)
Distance: 1.250 million light years
The Dumbbell Nebula M27 or Dumbbell Nebula in the Vixen was the first pla-
netary nebula ever discovered. On July 12, 1764, Charles Messier discovered
this new and fascinating class of objects. We see this object almost exactly from
its equatorial plane. If the Dumbell Nebula were seen from one of the poles, it
would probably have the shape of a ring and resemble the sight we know from
the Ring Nebula M57. This object can already be seen well in reasonably good
weather conditions at low magnifications.
2. Troubleshooting
Mistakes:
Solution:
No image
Remove dust cap from tube opening
Select eyepiece with lower magnification (= high-
er focal length)
Blurred picture
Focusing with the focus wheel
No focusing possible
Wait for temperature equalisation (approx. 30
minutes)
Bad picture
Never watch through a pane of glass
Observation object in the
viewfinder, but not visible
through the eyepiece
Adjust the viewfinder (see Part I - 8.)
Difficult tracking of the
axes via shafts
Balance telescope and counterweight (sh. Part
II - 3.)
Despite upright prism only
"crooked" image
Align upright prism vertically in the eyepiece
tube
Disposal
Dispose of the packaging materials by type. Contact your local waste-dispo-
sal service or environmental authority for information about the proper
disposal.
Observe the current legal regulations when disposing of the device!
Information on proper disposal can be obtained from municipal waste dis-
posal service providers or the Environmental Agency.
Do not dispose of electronic devices in the household waste!
According to the European Directive 2002/96/EC on Waste Electrical and
Electronic Equipment and its transposition into national law, used electrical
equipment must be collected separately and recycled in an environmentally sound
manner.
Batteries and rechargeable batteries must not be disposed of with household
waste. You are legally obliged to return used batteries and accumulators and
can return the batteries after use either at our sales outlet or in the immediate
vicinity (e.g. in the trade or in municipal collection points) free of charge.
Batteries and accumulators are marked with a crossed-out dustbin and the che-
mical symbol of the pollutant, "Cd" stands for cadmium, "Hg" stands for mercury
and "Pb" stands for lead.
