A
20 inch Alluna RC has been installed in the dome of the existing Zeiss
mount by members of IAS. The RC provides 51 cm aperture at a focal length
of 4.100 mm (f/8), which can be reduced to 3.000 mm using a reducer.
"The initial results with the RC20
are excellent. We thus have another tool its comparable in every way with
our other 20 inchers, in some respects it is even superior. "says Werner
