The MiniCat 51 is designed for photography enthusiasts who love wide-angle views. Its standout feature is an ultra-bright f/3.5 aperture, allowing you to capture faint nebulae or comets in a very short time. (The f/3.5 aperture lets in twice as much light as an f/5 aperture.)
The MiniCat uses the latest Petzval design with 6 lens elements, including 2 Super ED and lanthanum lenses to perfectly control chromatic aberration. It’s currently the only high-quality, short focal length 178mm f/3.5 astrograph telescope available on the market.
The MiniCat holds three unique patents, ensuring easy and perfect focusing along with coaxial image quality to prevent drawtube tilt issues caused by optical misalignment.
