Now also available is a RC-Telescope with 22 inch optic
Due to our customers’ frequent request for a telescope between the sizes RC24 and RC20, we have decided to introduce the RC22, a new telescope size at Alluna Optics.
Often, while there is a desire for a large RC24, there is either insufficient pivot range in the observatory or the existing mount cannot support the weight of an RC24 and its accessories.
|Binary star measurements with the 20-inch Alluna RC
Rainer Anton has already for several years created images of binary stars to measure position angles and distances. A good example of the high optical performance of Alluna telescopes.
|Alluna NA20 Astrograph now
with rotating top
Until now, only our 16 and 18 inch
Newtonian astrographs were equipped with a rotatable upper part. With this
function the eyepiece can be rotated to the desired viewing position either
for comfortable viewing in visual observation or practically upwards for
|50 kg load instrument -
not a problem for Alluna RC telescopes
The design of our telescopes milled
in a complex honeycomb structure from full-aluminium results in very high
stiffness and load capacity. In this way we facilitated that at the output
already instrument loads of 50 kg can be used without affecting the stability
of the OTAs and the mirror collimation.
|Alluna Carbon-Tube Ritchey-Chrétien
Certain applications require special
telescopes. Our Carbon Tube Ritchey-Chrétien telescopes are suitable
for use under extreme conditions when an open truss system is not suitable.
|Collimation of an Alluna
This guide describes how to use your
Alluna Ritchey-Chrétien telescope in a few steps and
adjust perfectly in a matter of
minutes. The collimation is best carried out in daylight.
All telescopes are adjusted on the
optical bench at the factory as well as possible.

|Ritchey Chretien or Dall
Often you read
things about Dall Kirkham telescopes that not always accurate and correct
statements. Accordingly, the Dall Kirkham telescope would be the ultimate
telescope, the "photo machine" for astrophotography with the best picture
quality, the highest available field and the best star images. Unfortunately,
the reality is different .....

|30-inch Dobsonian telescope
for the Swiss Alps
Author: "Bubendorf" Group
For decades, we four or five have
been observing on the Basel Jura Alps, where there are really dark places.
Naturally, the apertures of our portable telescopes have become increasingly
larger in the course of time.

install a new, larger instrument.
|Amateur solar observatory
in Langendorf / Germany
Report by H. Paleske
As a long-standing amateur astronomer,
active in the field of photography, I know that ultimately the aperture
