RiFAST Series

RiFast. A big, beautiful telescope at f/3.8. What else is there 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.
