The largest in the AVX series, the Schmidt-Cassegrain system telescope with a diameter of 28 cm (11 ") is a telescope of the Schmidt-Cassegrain system with a large aperture, despite the 28-cm diameter, the telescope is still compact and its usability is high diameter is enough to see many nebular objects, as well as to very efficient and effective observation of the planets of the solar system, thanks to the image of high contrast and resolution.

Equipped with a T-Adapter and T-Ring, the tube performs well as a serious astrograph
