The Ultra-Cat 108 features a 5-element advanced Petzval optical design and a fast f/4.8 focal ratio, delivering edge-to-edge clarity and vivid detail for capturing expansive celestial views. With a massive 60mm image circle, this telescope can support cameras with sensors as large as medium format. The innovative WIFD focusing design relocates the focuser to the center of the telescope, eliminating tube tilt caused by camera weight and accessories, while maintaining a fully unobstructed optical path for clean, precise image performance. Built with one ED and two Super ED glass elements plus lanthanum glass, the telescope eliminates coma, field curvature, and chromatic aberrations for excellent color correction and image clarity.
