A Large Spectroscopic Telescope for Space Object Identification

A transportable, medium-aperture telescope with a segmented spherical primary mirror might find use as a spectroscopic space object identification tool. Systems with spherical primary mirrors are easier to produce, easier to align and easier to keep in alignment but image quality suffers greatly thereby placing significant demands on corrector optics. We present the design of an improved corrector for spherical primary telescopes. This design is novel, simple and adapts equally well to post prime-focus applications or to Cassegrain-form systems with spherical primary and spherical secondary mirrors
