The earth is a celestial body on which volcanos can be found. The Pulvermaar
in the Eifel resulted from a steam explosion 15000 years ago.
In the Eifel, there are also volcano mountains. The Bausenberg at Niederzissen
is a particular well-proportioned one.
An atmosphere makes weather possible, sometimes more likely the bad one.
Sometimes, the weather is closer than the photographer likes it ...
In summer, the highest clouds on earth are forming. Ice in 80 km
height reflects the sunlight and gives "noctilucent" clouds.
When fast particles from the sun, the solar wind, come in the upper regions
of the air, through the magnetic field of the earth, they stimulate the local
atoms to give off light - the aurora shows up.
Mentioning the influences of our sun, we should not forget her surface.
Prominences, the gas eruptions visible at the rim, are among the biggest
structures known in connection with our local star.
Some threat to earth, but sometimes good to get a photograph of, are comets.
This "dirty snowball" is named Hyakutake and came close to the earth
to a distance of 15 million kilometers. The long ion tail makes the small dust
tail to appear small, while the blue-green coma is noticeable.
One year later, Hale-Bopp came along, whose bright dust tail outshined the
blue ion tail. The colour of the sky is caused by the light of street
lanterns, which is easily captured by the Fujichrome slide film.
One day, I had the idea that the surface of the water is a reflecting surface,
too, so I could get Hale-Bopp two times on one photograph..
An alternative for us: Mars. The dark regions are easily to recognize, in
opposite to the polar caps. The red colour is being caused by iron oxides,
a bit similar to rust.
The same phootgraph as before, but with enhanced colours. Here, one can
clearly see the bright polar cap.
Jupiter is a giant gas planet with a fast rotation which extends the clouds
to strings. The dark spot in the northern equatorial belt was unstable,
whereas the Great Red Spot in the southern equatorial belt isnīt only twice
as big as the earth, but also a few hundred years old.
The previous photograph with intensified colours. Here, the Great Red Spot is
clearly red.
Jupiter was object for my first night with astrophotography. A double shadow
transit, here visible in the left, was reason enough, whereas the double
transit was also watched at the beginning and to the visual spectator, due
to the low contrast.
The summer sky shows us the star covered galactical clouds in Cygnus. The
dark regions are dust, the red fluorescent ones hydrogen.
The central part of the Milky Way, taken with an underwater film. The dark
lanes are made of dust, which extends to the right, northern part of the central
bulge. The bright, red object below the middle is the lagoon nebula; at the
left, jupiter shines. Below the connecting line between the two, a meteor
left its trace on the 50 ASA film.
A normal film sees the sky in these colours. The red object is the orion
nebula (M 42), the object to the left of brightest star is the flame
nebula (NGC 2024). In both cases, hydrogen is glowing, which can be
identified by the red colour.
The orion nebula (M 42) is a 1500 light years distant gas an dust cloud,
which is stimulated to fluorescence by the stars in its middle. The dark grains
are just dust on the film. The nebula is a highlight of the winter sky.
The Omega nebula (M 17) is also a hydrogen cloud with dust, but is
located in Sagittarius and can be seen in summer.
In opposite to the previous objects, the dumbbell nebula (M 27) isnīt a
region of star formation, but a shell blown off by a dying star. On the
original scan, which doesnīt show the same colour as a print, the blue
regions of heavier elements accumulated during the life of the star are
better to be seen. The round shape gave the name to the class of the
"planetary Nebulae".
About 100000 very old stars form a globular cluster, which can be
photographed properly only through a telescope.
Open clusters consist of a few hundred younger and often hotter stars. Here,
two clusters are located close together.
The open cluster of the Pleiades (M 45) above the middle of the image can
also be seen fine in binoculars. The picture is not a photomontage, but good
luck. The helicopter put lime to the wood at the day, and was parked then.
With its 2.3 million Light years, the Andromeda nebula (M 31) is the most
distant object that can be seen with the unaided eye. For taking a photograph
of this galaxy, a standard lens is sufficient. Here, a 200 mm telephoto
lens was used.
The two close galaxies M 81 (at the right) and M 82 (at the left)
had an encounter many million years ago, which lead to dust lanes. In
binoculars the lanes are not visible, but it is possible to see the
different shapes of the galaxies.
The galaxy NGC 4565 is located in the Virgo galaxy cluster and looks
thin even in a telescope. A dust lane devides the object decoratively in two
parts.
Also only to be watched with a telescope are these two galaxies. Right of
the middle, there is NGC 4656, which looks like a mirrored
"S" with brighter middle and a very weak second half. In the roght
upper corner, there is NGC 4631, which is seen fromm the side. The core
with its copper hue can be seen better on the original slide.
