600mm (24") Cassegrain and Ritchey-Chrétien System
Cassegrain and Ritchey-Chrétien (RC) telescopes are used by professional observatories, research institutions and universities. Our telescopes are designed by Philipp Keller, a German physicist and optical engineer. The telescopes are made in open truss construction style with CFK-tubes and precision optics from LOMO Optics. Customers can choose to opt for the optical sets or the complete telescope system which can be set up in an equatorial or alt-az design. In combination with a focal reducer or field flattener designed by Philipp Keller, these instruments can also be used for large CCD sensors with diameters of 150mm and more and still display pin point stars all the way to the corners.
