MiniCat 51 f/3.5
Category: Refractor Telescope
Explore the Stars with the William Optics MiniCat 51 WIFD Telescope
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.
For perfectionists in astrophotography, we recommend using BXT software after stacking your images to achieve flawless correction of peripheral star points.
The MiniCat 51 manual can be found here.
