MiniCat 51 WIFD
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.

Widest Astrograph //
// Sharpest Lens
MiniCat 51 can also be used as a regular photographic lens. Its telescope-grade APO optics deliver sharper images and more accurate color.
Correctable Corner Imperfections
Due to the nature of MiniCat’s fast aperture optical design, edge stars may not be as round as with other RedCats. However, our tests show it still outperforms conventional lenses. With aberration correction software like BXT, peripheral distortions can be perfectly corrected on APS-C sensors, while Full Frame may need some fine-tuning for even better results.
