About the Observatory and this Society
These www-pages give you some information about the activities of the
different workgroups of the observatory, especially about the
purpopses of this non-profit-making supportive society.
Observatories are valuable institutions for the scientific education in
of students and adults and should therefore be promoted.
The managing committee is gladly at your's disposal
to answer your questions.

How Came the Observatory to the Town of Laufen?
In the early seventies the administrative district of Laufen inherited
a complete observatory equipment and a small wooden dome for the local
grammar school. Because there
was only a quite steep ladder to the observatory and room was only
available for a small number of visitors, no public access was possible.
In the course of some reconstruction of the school building in the years
1987/88, the opportunity was taken to get more spacious rooms and a new fibre
glass dome for the observatory.
In the early years the observatory was used by some astronomy classes
only. In 1986 some students of the grammar school founded the
Astronomische Arbeitsgruppe Laufen
e.V. (AAL), which was granted access to the observatory after the completion
of the reconstruction in 1987/88. From there on the observatory was open to
Together with the AAL the head of the school's
Gerardo Inhester, arranged the
first open day in 1989. Since then every year an open day with
about 200 to 300 visitors is held. Besides that we offer an
observation of the sun or an astro evening event
every first Saturday of each month which everyone is invited to attend.
Up to May 25th 1996 the main instrument was an 8'' refractor with a focal
length of 133cm of Carl Zeiss, Jena. The age of the refractor was hardly to
be estimated because some main construction plans were supposedly destroyed in
World War II. With regard to the technology at that time there was no
coating. Because the aperture was quite large for a refractor there was
a strong chromatic abberation.
The mount was around 25 years old. Thus it was technically out-dated and
because of some smaller construction faults hardly usable for more
The set of oculars, also dated around 1930, was piece by piece replaced
by common oculars during the last years. This could only be accomplished
by the financial support of the parents' council.
From the above description one can easily draw the conclusion, that
the equipment was not well suitable for serious astronomical observations
as part of astronomy classes. This was a pity because few grammar schools
have their own observatories anyway and there is a great public interest
in astronomy as one can see from the "comet fever" in the last years.
After the very expensive reconstruction of the school building
there was no hope for further financial support by the autorities of
the administrative district. The annual budget only meets the regular
expenses and equivalates to the value of some technical books or an ocular.
Therefore the help of this supportive society was useful.
With the money we got from foundations, banks, companies
and surrounding towns we were able to buy a Meade 16'' LX200 with a
cardanically mounted 5'' apo guide telescope. Furthermore the observatory
could be supported with a binocular eypiece holder from Zeiss, a 0.5
Å H-alpha-filter and necessary eyepieces. Now the equipment is
suitable for serious work and education in astronomy as part of the scientific
eduacation of the students. Additionally even newbies in astonomical
observations visiting the observatory are now able to admire the beauty
of the starry sky without
Ames of the Society in the Future
To buy an appropriate CCD camera we ask everyone interested in our work to
support the society by a donation. We are a non-profit-making society and
thus every donation is tax deductible.
Another aim in the future will be the support of students doing
astronomical research during their education exspecially in higher grades.
