Alluna 牛顿反射望远镜


Alluna Newton Astrographs are high-end telescopes uncompromisingly oriented to highest optical and mechanical quality. As pure astrograph or as robust observatory telescope for visual use or for research, the Alluna Newton astrographs are the right choice for all application areas.

For the optics, the core of each optical telescope, we do not engage with any experiment. We use exclusively high-quality optics of our own production. The tube is, same as in our RC Telescopes, made of a honeycomb-pocket structure. In order to allow the best possible insight the tube's upper part is rotatable in a highly precise socket.

Newton Astrograph Optics
A perfect parabola shape of the main mirror and in addition a low surface roughness are the preconditions for the high-contrast pictures of a Newton astrograph. We guarantee, that all Newton optices comply with these rewuirements. Alluna Newton astrographs are available as fast-lens f3.8 systems in four different sizes, 16, 18, 20 and 24 inches as standard. In case you require a higher light intensity, we can offer systems with openings of down to f3.0. With a 3 inch Wynne corrector you may achieve a perfectly corrected field of up to 45 mm.


Newton Astrographs CNC Carbon Truss OTA
You will hardly find a Newton astrograph featuring the same precision down to the last detail as our Carbon Aluminium Truss astrograph. All bigger parts are cut from solid aluminium. Thanks to the honey-comb pocket structure we achieve enormously stable and warp resistant systems even in a leightweight construction. 
Using most modern CAD systems is indispensable for construction and design of our high-quality telescopes. Complex single components and sub-assemblies are modelled exactly upon the requirements and assembled virtually before production. Thus all parts can be optimised with regard to weight, stability and expansion behaviour. The comprehensive FEA (Finite element analysis) additionally helps to analyse all supporting parts by means of stress simulations.
