Product Description

Officina Stellare Veloce Astrograph

The materials Officinia Stellare uses in their premium quality telescopes are mostly aluminum and carbon fiber because of their lightness, their mechanical and thermal properties and for the optimal resistance to environmental conditions. 

Veloce Astrograph Officina StellareAll 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 holding systems for both mirrors, the spider, rings and all the structural components, even the smallest, are CNC machined from a single block of 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 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. 

 The ultra fast Riccardi-Honders astrograph represents the only true innovation in optics of the past fewyears.Born from the intuition of the Italian designer Dr. Massimo Riccardi, as a variant of the original Hondersdesign, this new configuration achieved the purpose of combining the extremely fast F/3 focal ratio with aflat, very large diameter, imaging field.In addition to these amazing optical performances, the Veloce RH Series instruments are distinguished byan impressive compactness, unique in its kind, making them very easy to transport and easy to install ontypical amateur mounts.The Veloce RH series produced by Officina Stellare are the only instruments in the world designed personallyby Dr. Riccardi, inventor of theRiccardi-Honders optical design.The Veloce Series of telescopes are theperfect instruments for those astroimagerswho are searching for a very large,corrected, field. Large nebulas or starsfield will be deeply reproduced withvery high resolution and full details. Thevery fast focal ratio allows for the use ofvery narrow band filters keeping shortthe exposure times, and the widest possibleimaging field greatly facilitates therealization of variable stars, asteroids orextrasolar planet search surveys.



The back surface reflection of the primary mirror (called Mangin) is the main characteristic distinguishing the Riccardi-Honders optical design. Combining the reflecting and double refracting action (the incoming light passes twicethrough the full thickness of the primary mirror) of this element it is possible to obtain a greater optical correction while maintaining the instrument extremely compact.The optical design includes a full aperture corrector plate and it is completedwith a two element flattener group situated before the focal plane. This complexoptical system guarantees to the astroimager a greater off-axis correctioneven with a very fast F/3 focal ratio.Another important factor is that the Riccardi-Honders optical design contemplatesspherical surfaces, this results in the advantage of greater ease ofcollimation and in its stability over the long term.



Thanks to the most recent optical design software which allows to verify the focus shift caused by ambient temperature variations, it was possible to identify and produce the mechanical components optimized to allow for thermal compensation of these variations. This guarantees a stable focal position during imaging sessions, an essential condition when using instruments with such a fast focal ratio.All the mechanical parts are produced using only the finest materials available, such as special lightweight aluminum/Ergal, stainless steel, bronze and particular alloys for thermal compensation. The tube is designed and optimized with CAD and computer support modelling to achieve the best rigidity and lightness. All parts are full CNC machined to guarantee the best possible precision.The high resistance anodization is chosen for unbeatable resistance to environmental conditions.The Veloce Series can also mount a piggy back support specially designed by Officina Stellare for a stand alone autoguider.Finally, the great mechanical extraction of focal plane position allows to use complex imaging trains, both with CCD or the more popular digital reflex cameras.


Wrapping this together, the Officina Stellare Veloce Astrograph is simply a product that cannot be overlooked. Managing to incorporate the latest high quality optics with Riccardi-Honders optical designs to obtain accurate views along with the amazing computer software and high quality materials for precise and accurate results, it is quite remarkable the Veloce astograph is only 18 pounds!
