Item # OF-VRH350
  • The Officina Stellare Veloce RH 350 is an extremely fast, wide field, 13.8" Riccardi-Honders Astrograph. Innovative, Officina Stellare exclusive, primary Mangin mirror optical design by Massimo Riccardi.

  • The Officina Stellare Veloce RH 350 has 350 mm of clear aperture, and an incredible ultra fast, wide field, F/2.8 focal ratio. The optical tube assembly is made of a special thermo-compensated material for quick temperature equilibrium.
  • The Officina Stellare Veloce RH 350 includes three fan primary mirror ventilation system, a retractable dew shield, and two Losmandy dovetails, one of which has tip/tilt functionality.
  • Images show the RH 300 model. For more information on the largest telescope in the Officina Stellare Veloce series, contact our telescope experts at OPT.



Officina Stellare Veloce RH 350 - Riccardi-Honders Astrograph Telescope

The Officina Stellare Veloce RH 350 Riccardi-Honders Astrograph is a premier, innovative, Officina Stellare exclusive! Just check out the primary Mangin mirror optical design, large front full aperture corrector lens and near zero expansion ceramic glass for the primary and secondary mirror. It even has two spaced elements for the rear group. We're talking about 350 mm of clear aperture, and an incredible ultra fast, wide field with an F/2.8 focal ratio.  

All the mechanical parts for the the OTA are machined using CNC computer assisted machines and from a whole block of aluminum to guarantee the best possible precision. Also the carbon fiber components are produced following strict specification and tolerances. Each part has been computer designed and optimized for the best structural performance, rigidity and lightness. The tube is made of true carbon-graphite fiber obtained with the use of high vacuum process, allowing us to obtain the best stability of the focus vs temperature changes still maintaining the best structural rigidity and lightness.

Great care is taken in the making of the rear holding cell of the primary mirror. The entire rear cell for the primary mirror is figured to have the best rigidity/weight ratio and for the fastest possible thermal stabilization between the environment and mirror. The convection and thermal irradiation are greatly improved with the use of three high quality axial fans in the back of the cell.

Great attention has been applied to simplify the collimation between the mirrors resulting in a stable, efficient but easy to use system. The collimation is accomplished by acting on just three points (the minimum required points to generate a single plane) using a special, great diameter preloaded bolts (one for each point). This results in a single hand use, simply turn the bolt left or right to move the mirror back and forth (no more complicated operations using push pull screws and locks) in a very intuitive way. Finding the correct positions is a snap. The mirror borders uses an opaque, circular mask to avoid any undesired light scattering. The light shields for the primary and secondary mirrors are computer designed and optimized to ensure complete illumination of the field still maintaining a complete protection from stray light. Inside the light shields there are also micro baffles that reduces, coupled with an opaque painting of the surfaces, to nearly zero any possible parasite stray light. In some cases and for particular applications, the light shield for the secondary mirror is made using a special layout that maintain the efficiency of the system while reducing the obstruction for the system. The back plate of our telescopes comes standard with a system for adjusting the planarity of the focal plane in order to compensate for any small misalignment in the imaging train, always unwanted and annoying specially on today’s large CCD cameras.
