    Officina Stellare Veloce RH 300 f/3 Recardi Honders OTA Telescope

    The Officina Stellare Veloce RH 300 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 300 mm of clear aperture, and an incredible ultra fast, wide field with an F/3 focal ratio and 900mm focal length. Add to that a flat 60 mm diameter field, with 6 micron maximum star spot size.

    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 especially on today's large CCD cameras.

    • I have a big concern with the warrantees on telescopes. I am not rich by any means I am a college student and saved my penny for quite sometime to purchase my celestron cpc 1100 hd which only has a 2 year warranty, which i think is insane.. For this scope

      Chris, The Celestron CPC 1100 Edge at $3799 does have a warranty of two years. That is actually more than most telescope manufacturers. I personally have a CPC 1100 SCT which I bought used and is working fine after having it for two years. I may be j
