3. Namibia is located directly at the Tropic of Capricorn. Therefore
many constellations and other astronomical objects are right at the zenith, so
they are easy to observe. Short twilight allows long observation periods.
4. The countries topographical characteristics: Main parts of Namibia are on the
African plateau that by average rises to 1500m above sea level. Some peaks in
the mountain range at the border of the Namib even reach heights of far more
than 2000m.
With its location on a plateau in an elevation of 1000m on an average and only
3.5 parallels from the Tropic of Capricorn, the Vogelstrausskluft offers perfect
conditions for stargazing. Depending on the site a panoramic view of up to 360°
without any hills or trees is possible here. The farm area is shielded by the
mountain range close to the Konkiep River - which however is only visible in the
far distance - and sits close to the dry desert of the Namib in a part of Namibia,
where rain even in summer is rare.
During the last couple of years among astronomers Namibia more and more
came into the centre of interest. Aside from smaller observatories in the
meantime also bigger facilities are built here, like the H.E.S.S. Array of
the Max-Plank Institute of Heidelberg. What makes Namibia so special for
this purpose? There are numerous reasons why Namibia should be chosen as an
observation point:
1. The country is only sparsely populated. Only 1.7 million people live in an
area of 824 000 km2 (which is about three times the size of Germany). Therefore
light-pollution is very low to not existing and also air-pollution that would
blur the sight can be neglected. Stars down to a size of 7 can be watched with
the naked eye.
2. The humidity is very low. The cold Benguela current alongside the
coast of South-West Africa and the dry deserts of the Namib and the Kalahari let
only little humidity reach the inner territories. During the months of May to
August, in winter, no rain at all is falling and rarely one cloud is covering
the sky. Outside of Namibia these special conditions only can be found in some
parts of the South-American Andes, which however are far more difficult to
access.
