New 20 inch optics
for astronomical camera IAS observatory on Hakos / Namibia
The association "International Amateur
Observatory" (IAS) provides amateur astronomers the opportunity to observe
on their own, photograph and carry out scientific work on large telescopes
under optimal skies. The primary objective of the IAS is to allow amateur
astronomers and scientists access to powerful telescopes under the best
astronomical conditions. The southern sky is the focus of attention. The
members have access to telescopes of different sizes on the grounds of
the guest farm Hakos and directly on Gambsberg in Namibia.
For the new astrocamera (AK-3) which
replaces an existing astrocamera (AK-2), the International Amateur Observatory
IAS decided again for a primary mirror from Alluna Optics. The 510 mm mirror
with an aperture of f3,8 can be operated with different reducers/correctors.
Focal lengths of 1885 (F3.7) or 1404 (f2.8) are attained. In addition,
Barlow lenses or fluoride Flat Field Correctors can be used for extensions
of the focal length.
The new optic of the AK-3 is already
the fourth major specular reflector from Alluna being used in West Africa.
In addition to the AK-3, a 500 mm Dobson and a 600 mm telescope, the 710
mm telescope with Alluna optics will soon go into operation at the top
of Gamsberg.
