TELESCOPES AND INSTRUMENTS "RiFast"

RiFast. A big, beautiful telescope at f/3.8. What else to say?

Devoted to astrophotograpy, the RiFast family has an unique optical scheme, proprietary of Officina Stellare, another creation of our master optician, Massimo Riccardi. The tree-lens field flattener is the real masterpiece of this telescope. The primary mirror is aspherical and the secondary mirror is spherical. A precise design choice to make collimation easier.
