Description

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 three-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.

Diffraction-limited over a wide and flat field, the RiFast design will push any camera to its limits... and will do it FAST! The extraordinary f/ ratio allows a higher productivity per night, a significant factor for surveys, SN search, asteroid control, and many other fields of modern astronomy.

The central obstruction is about 50%, but still smaller than similar designs, that simply can't compete under any point of view. The visual contrast is very good, thanks also to the special ultra-dark paints we use.

The corrector group is very close to the focal plane, so chromatic aberration is undetectable.
