International Amateur Observatory e.V. 

The 20-inch 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).

28" telescope at the observatory Gaisberg/Austria

After 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 instrument.
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. ...

30-inch Dobsonian telescope for the Swiss Alps

For 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 ...

A 410mm Newtonian reflector for the Amateur sun observatory in Langendorf

As 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.
