Officina Stellare is the only manufacturer in the world to offer a complete catalog of "standard" telescopes and astrographs, to meet any need for professional astronomers, institutions, universities, astronomy clubs and of course the most advanced amateurs.

With the choice of three different optical schemes for telescopes, all available in the 400 to 800 mm aperture range, and the extraordinary family of "RH Veloce" astrographs (200 to 350 mm aperture) it is really unlikely we don't have the instrument that fits your need.

All telescopes have a carbon/aluminum structure (full carbon as an option) and offer the choice between standard optical glass and near-zero expansion ceramic glass for the mirrors. All models are available with 400, 500, 600, 700 and 800 mm primary mirror diameter.

Any optical part is polished by our opticians in our optical shop in Occhiobello.

All telescopes share the following mechanical characteristics:

  • Two (optionally four) Losmandy or 8" dovetail plates, to connect the telescope to your mount, or to accommodate accessories.
  • Computer optimized baffles.
  • Focal plane tilt adjusting.
  • Optional shutter to protect the primary mirror.
  • High precision spherical joint and high strength carbon tubes in the truss structure for zero-backlash assembly and extraordinary rigidity.
  • Double concentric light shield for the secondary mirror/spider support.
  • Radial micrometric adjustment for the secondary mirror support.
  • All collimation screws are spring-loaded, with lock if needed.
  • Zero image shift secondary mirror movement, with electronic/PC control (optional on smaller telescopes, standard in the big ones).
  • Special ultra-dark and ultra-opaque space-grade paint for all sensible parts. Space grade glue for glued parts. Space-grade rubber for all seals.
  • Unique mirror supports design.
  • Wide choice of focusers, filter wheels, and optical train accessories in general.
  • Customization available.

Our lines:

Our most professional line, a fine tuned Ritchey–Chrétien design.

ProRC Purely reflective scheme, low obstruction, usually f/8, it is the perfect choice for professionals. Focal reducer and field flattener are available as options. Longer f/ ratios upon request.

The "universal" telescope.
With a balanced f/7 focal ratio and the 2-lens field flattener

RiDK it offers a good compromise between obstruction and focal ratio. Two-stage light shield as standard on the secondary mirror, allows lower obstruction for the same focal plane illumination. Reducer available for f/5 operation.

With a jaw-dropping f/3.8 focal ratio, the RiFast are
the ultimate telescopes for wide field astrophotography

RiFast The unique 3-lens field flattener allows wide flat focal planes, 80 mm or even more (!) in diameter.
Two-stage light shield as standard on the secondary mirror.

A family of astrographs (200, 250, 300 and 350 mm),
all at f/3 (only the 250 model is f/5.6)

RH Veloce Intended primarily for the advanced amateurs, they have been used also by professionals for wide field surveys.
Named "the Holy Grail of astrophotography" by Sky&Telescope, they are the real heritage of the glorious Schmidt cameras, ready for the 21th century CCDs.
