RC telescopes use hyperbolic mirrors to eliminate optical errors like coma and chromatic aberrations off-axis while producing the flattest focal plane possible without lenses. I was over at Norm's shop two weeks ago. Consumer-grade telescopes can have imaging defects such as color fringing a kind of chromatic aberration that happens when the lens is unable to bring all wavelengths of color to the same focal plane. With a 70 mm image circle, the RC700 is designed to excel at imaging on large-format CCD cameras. Observatory Dome, Explora Dome - Explora Dome I 8ft.
