|The best proof of quality
and reliability is satisfied customers. And that is why we are quite proud
that more and more astrophotographers, research centres, institutes, universities
and public observatories worldwide use optics and telescopes from Alluna
Here is a small selection
of recent telescope projects.
Ritchey-Chrétien telescope at one of the highest telescope locations worldwide
A challenging task, the installation of this Alluna-Optics telescope on one of the highest areas on earth. The observatory is located at an altitude of 5100 meters. The district in western Tibet is sparsely populated and it often makes nice and dry weather. However, the temperatures can drop to below minus 30 °C. The plan is to start the observation during the year 2016.
Alluna RC 16 telescope / Japan
The delivery of this RC16 telescopes with Zerodur optics performed early 2016. The telescope is used on a Mathis Instruments MI-500 fork mount. The width of the mounting plates have been adjusted accordingly existing Mathis Mount. Additional mounting plates allow the use of guide tube and weights. The installation was carried out by our representative in Japan.
RC 20 telescope for new observatory of Sacred Heart College Perth / Australia
Alluna Optics delivers RC20 Telescope for a new observatory on the grounds of Sacred Heart College in Perth Australia.
The new observatory in the school is currently under construction, with completion beginning of 2016. The telescope will be installed in a 5 metre diameter Sirius Observatory dom.
Australia 2015: In year 2015 a total of three RC20 and one RC16 telescope have been delivered to Australia. Two of them in the vicinity of Sydney / New South Wales and two near to Perth / Western Australia.
Currently is another Ritchey-Chrétien telescope for Australia with us in manufacturing. This telescope goes to a private customer near Perth. Delivered is in the second quarter 2016.
Because of the low population density and the favorable climate are large parts of Australia's best suited as a location astronomical telescopes.

for photometric and spectroscopic observations of stars and galaxies. The
observatory also serves as an observation and training centre for students
as well as the national education and awareness program to promote the
astronomy and space travel.

in Japan. To accommodate a larger instrument load of up to 50kg the back
of the telescope has been adjusted accordingly. In addition, the telescope
received a Zerodur optics with extended back focus at the client’s request.
one of the projects of Hiroshima Astrophysical Science Centre, Hiroshima
University. A new robotic three colour simultaneously imaging camera is
used here. The main purpose of this imaging is to show activity of transient
objects. Together with other institutions, such as the 1.5-meter Kanata
telescope a global network was created for the continuous monitoring of
transient objects. Commissioning for testing 2014 on the1.5 meter Kanata
telescope. In 2015, then the installation will be placed at its final location
in Tibet at an altitude of 5100 meters.
RC18 Telescopic in fork design for customers in Beijing/China
After two Alluna
RC18 telescopes have already been successfully commissioned in 2012 near
Beijing for operation, now a repeat order for another identical 18-inch
Ritchey-Chrétien telescope has been placed. In the greater Beijing
area now there are a total of four Alluna Ritchey-Chrétien telescopes
for scientific operations.
for University of Birmingham/UK
provides an RC20 telescope for the School of Physics & Astronomy, University
of Birmingham. The main application is the education of students, astrophotography
and the use of a large spectrograph.

Paramount ME Astronomical Association Ursa/Finland
Astronomical Association is the oldest and largest club for amateur astronomy
in Finland. Ursa currently has 17,475 members. The Ursa goal is to promote
astronomical education in Finland and interest in astronomy. The Ursa Astronomical
Association wants to provide the best conditions for amateur astronomy;
the Alluna Ritchey-Chrétien telescope on a Paramount ME is used
mainly for photography.
RC18 telescopes for an observatory near Hong Kong/China
provides two identical RC 18 telescopes for observatories near Hong Kong.
Unfortunately, we have no evidence of the use of the telescopes.
Alluna Ritchey-Chrétien commissioned in Namibia
Amateur Observatory e.V.
Alluna RC telescope was installed in the dome on the existing Zeiss mount
by members of IAS. "The initial results using the RC20 are excellent. We
thus have another tool which lacks nothing compared to our other 20 inchers
and is even superior in some ways," says Werner Roßnagel (IAS). More
information and astroimages on the website of the IAS
In September 2015, the RC20 of the Zeiss-mount is moved to a modern Mount of GM4000HPS. The column was replaced with a more stable version. Without Guiding exposure times of 10 minutes have already, with the GM4000 mount at 3,000 mm focal length possible.

RC20 for Ataturk University Erzurum/Turkey
is the new telescope of the University of Erzurum and serves scientific
research and training in the field of astronomy and astrophysics. The observatory
is located at a high altitude and due to the small number of cloudy days,
the 20-inch Ritchey-Chrétien telescope can be used efficiently all
year round. The inauguration took place in September 2012.
Ritchey-Chrétien telescopes again witnesses in 2012 an increase
in the amateur area
Also in 2012
more Alluna Ritchey-Chrétien telescopes of sizes 16, 18 and 20 inches
were delivered to private amateur astronomers. For the most part, the telescopes
are used for astrophotography graphical applications with large CCD cameras
and our 4" field corrector and/or .74x reducer. The customers came from
different countries such as Austria, France, Belgium, Spain and Germany
as well as from Asia.
The new telescopes
in the amateur and semi-amateur scene are attracting ever greater interest
and we take particular pride in this.
RC16 for Kinmen Educational Remote Observatory, Taiwan
In 2012 on
the island of Kinmen belonging to Taiwan in the South China Sea an Alluna
RC16 telescope was installed on a Paramount ME. The telescope is used in
addition to making astrophotographic recordings, to train students in the
field of astronomy.

optics for astronomical camera at the IAS observatory on Hakos/Namibia
association "International Amateur Observatory" (IAS) provides amateur
astronomers with the opportunity to observe through large telescopes under
optimal skies by themselves and to carry out scientific work. The primary
objective of the IAS is to give amateur astronomers and scientists access
to powerful telescopes under the best astronomical conditions. The southern
sky, which is not visible from Central Europe, is the focal point of interest.
The members have access to telescopes on the grounds of the guest farm
Hakos and directly on the Gambsberg in Namibia.
at the observatory Gaisberg/Austria
a 15-month planning, construction and commissioning phase, it is now finally
ready. The new 700 mm Newtonian telescope. After the 600mm telescope met
with some observations on its technical and aesthetic limitations, the
decision was made about 1.5 years ago, to design and build a new, larger
Here the currently possible maximum
optical aperture and technical feasibility should be the measure for the
design of the new telescope. The mechanical assembly and adjustment is
now complete and the device is ready for further research work. With this
instrument it is possible to now to observe objects that are 36% fainter
than was possible with the 600mm telescope. ...
Dobsonian telescope for the Swiss Alps
decades, we observed through four or five in the Basle mountains of Jura
or in the Swiss Alps, where there are really dark areas.
Naturally, the apertures of our
portable telescopes have become increasingly larger over time ... 25 years
ago we started with the construction of 6- and 8-inch models; following
that we contented ourselves with 10- to 12-inch models (all self constructions:
Newton; Zerodur; Optics on portable, tracked frame assemblies). Ten years
ago, we bought an 18" Dobsonian, and now we have bought a 30-inch model.
As trivial as it sounds: one sees with a larger aperture ...
Newtonian reflector for the Amateur sun observatory in Langendorf
a long-standing active photographic amateur astronomer, we know that ultimately
the aperture and the quality of the optics as well as the atmospheric seeing
determine the quality of high-resolution images. After three decades of
experience with refractors the feasibility limits were attained in relation
to the lens aperture (d = 225mm), More resolution could only be realized
with acceptable cost only using mirror optics.
