Abstract
A new family of 2 mirror unobscured telescopes of compact "Schiefspiegler", off axis Cassegrain geometry, incorporating aspheres, tilted and decentered secondary, and tilted focal surfaces, will serve as fast, high resolution, moderately wide field telescopes / collimators. Designs range from f/5 to f/16. The nCUB designs provide a focal surface normal to the gut ray for visual use. The tCUB designs provide collimator telescopes with focal surfaces tilted so that any light reflected from the reticle is eliminated.
