Amongst the latter were a Dollond 46-inch achromatic, aperture 3¾ inches, and the one Cassegrain reflector constructed by Short, of 24 inches focus and 6 aperture, known among opticians as 'Short's Dumpy.'
Kutter was awarded two golden medals at the Venice Biennale and he invented the well-known Schiefspiegler telescope which is a modified Cassegrain reflector featuring superb optical definition due to an off-axis secondary mirror.
The telescope has a compact modified Cassegrain design with a large 0.69 m secondary mirror, which gives it a very wide field of view: its single, dedicated instrument, a 268-million pixel imaging camera, can photograph 5.7 square degrees of sky.

A 41-cm (16-inch) Boller and Chivens Cassegrain reflector originally housed at the Harvard-Smithsonian Oak Ridge Observatory in Massachusetts is available for public use at the National Air and Space Museum's Public Observatory Project on the National Mall in Washington, DC.
