The RiFAST 700 is an astrograph with a new revolutionary optical design proprietary of Officina Stellare, designed by Massimo Riccardi.

 

OPTICAL DESIGN

The primary mirror is aspherical and the secondary mirror is spherical, a precise design to make collimation easier. The RiFAST includes a 3 elements flattener of which 2 are aspherical and it is placed near the focus position to avoid any chromatic aberration.

The telescope is a native f/3.8 with a flat field up to 80mm. The scope has the option to be used with a dedicated 0.78x reducer (XTFR078), bringing the focal ratio down to f/2.96.

 

MECHANICAL PERFORMANCE 


The collimation is stable as ever before due to an improved mechanical design. Every RiFAST is tested under the sky and is tested in Officina Stellare's factory, ensuring a perfect collimation.


The secondary mirror is motorized for focusing, leaving the imaging train fixed as screwed to the backplate, a good solution for heavy cameras and accessories. It is also possible to install a tip-tilt mechanism. 
Remote observers can upgrade their RiFAST with a primary mirror shutter to avoid moisture and dust deposit on the telescope’s mirror when not in use.
