Overview of the RH Veloce Telescopes:

The RH Veloce is a really unique design, and uses several unique solutions, created by Riccardi and Honders. The RH Veloce uses a double front lens that is weakly convergent, and the primary mirror is a Mangin mirror (from the name of its French inventor). A Mangin mirror is a mirror that is coated on the back surface, not on the front. The light passes through the glass, is reflected by the coating and then passes again through the glass. For this reason, a Mangin mirror is called a refractive-reflective optical element, and opens exciting possibilities to optical engineers. This complex design includes also a corrector group before the focal plane, achieving performances impossible otherwise, with extraordinary fast photographic performances over wide focal planes.

A curiosity about the RH Veloce: since the double frontal lens is convergent, the Mangin mirror is smaller than the nominal diameter of the scope, while the meniscus itself is bigger than the nominal diameter, to ensure a good illumination over the wide field of view of such scopes. For example, the 200 mm model has a 220 mm meniscus and a 190 mm primary mirror. The secondary mirror is a separated piece of glass, or it is made coating the middle of the meniscus, depending on model.

The RH Veloce frontal lens is made in Germany under Officina Stellare specifications.

Veloce in Italian means fast, to indicate its primary vocation: to be a great astrograph capable of stunning performance.

A big evolution step of the iconic Veloce RH200 AT: You can now expect an even better large field photographic performance thanks to an innovative light baffles coating. It will give you a much better reduction of ghosts and scattered light.

The Veloce RH 300 AT offers an incredible fast f/3 focal ration with a 60mm corrected field, small stars, great transportability, great optics and great mechanics: this is the best professional astrograph to reach new horizons!

Officina Stellare developed the Veloce RH 300 AT without compromises both on mechanically and optical, using only premium materials (alluminium 6061/7075, titan, bronze, stainless steel, carbon fiber) and CNC machines to work parts from solid blocks. This offers the best precision available in the market today. When they selected the materials for each Veloce RH 300 AT component, Officina Stellare considered the derivated problems from thermic dilatation and environmental conditions. This makes the RH 300 AT stronger and capable to get the best performance every time it’s used, providing a stable focal plane, fundamental when operating with a so fast focal ratio, thanks to a athermal design.

The Veloce RH 300 AT is still transportable with a weight of only 28kg and convenient to use thanks to compact size and great mechanic. Three fans helps to reach the right working temperature for the primary mirror.

The corrected and illuminated field is 60mm. If the user needs to compensate the small misalignment in the imaging train, is possible to adjust the planarity of the focal plane with 4 screws located on the back plate.

Collimation is not only stable, but also intuitive: primary mirror cell has 3 points with large diameter preloaded cup springs (one for each point) operated from oversized bolts. What’s the advantage of this new solution? Well, you only have to rotate right/left each bolt to reach the collimation. No more difficult pull/push screws and locking screws as well.

Light scattering are avoided with a circular mask placed on mirror borders. Inside light shield Officina Stellare uses micro baffles, combined with special opaque dark painting and flocking, nearly to zero the possibilities to get stray light.

The Veloce RH 300 AT offers an incredible fast f/3 focal ration with a 60mm corrected field, small stars, great transportability, great optics and great mechanics: this is the best professional astrograph to reach new horizons!

The RH 300 AT is a real astrograph, designed to be the best companion of advanced amateurs and professional.
