About the Officina Stellare “Veloce” RH 300 Riccardi-Honders Astrograph…
The materials Officinia Stellare use in their premium quality telescopes include ultra purity single block machined aluminium and carbon fiber because of their lightness, their mechanical and thermal properties, plus optimal resistance to environmental conditions. Mechanical components for the Riccardi-Honders Astrograph OTA are machined using CNC computer assisted machines from full block aluminum to guarantee superior precision. Carbon fiber components are produced following strict specification and tolerances. Each component for Officina Stellare Veloce RH 300 is computer designed and optimized for the best structural performance, rigidity and lightness.
When it comes to the Officina Stellare “Veloce” RH 300 Riccardi-Honders Astrograph , the holding systems for both mirrors, rings and all the structural components, even the smallest, are CNC machined from a single block special aluminum (6061/7075, Ergal and Anticorodal), stainless steel, titanium and brass. The tubes are made of true carbon-graphite fiber obtained with the use of high vacuum process, allowing Officina Stellare to obtain the best stability of the focus vs. temperature changes still maintaining the best structural rigidity and lightness.
Significant care is taken in the making of the rear holding cell of the primary mirror for the Officina Stellare “Veloce” RH 300 Riccardi-Honders Astrograph. 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. Great attention has been applied to simplify collimation resulting in stable and efficient but easy to use system. The collimation for the Officina Stellare RH 300 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
Light shields for the primary and secondary mirrors of the Officina Stellare Veloce RH 300 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 the telescope 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.
It doesn’t get any better than this!
Officina Stellare “Veloce” RH 300 Riccardi-Honders Astrograph Features…
