Almost everyone knows about the high level of innovation and technology that comes with any OS product, it's clear at first sight.

Many know that OS have introduced new optical designs for todays demanding marketplace amongst both amateur astro imagers and professionals.

A key part of OS philosophy is, trying to be "smart" and one step ahead.

So: they did it again!

Many of OS customers are asking why they don't have a Dall-Kirkham or a CDK telescope in our arsenal of products, well that's because of their way of thinking.

Many other manufacturers just take one classical optical scheme and add some sort of corrector to it, just to have a flatter field and/
or a better spot size, OS always try to make things better.

The RiDK 305 (Riccardi Dall-Kirkham) represents the new reference point for all modified Dall-Kirkham instruments available on the market.

The unique experience and creativity of Massimo Riccardi, Chief Optical Designer at Officina Stellare, gives birth to a new 305 mm diameter astrograph of superior performance and image quality.

The results are simply amazing: a system delivering more than a 60mm large corrected and flat field that is over the entire field diffraction limited.
And, more than this, over a spectral range from 380nm to 2000 nm!

These outstanding optics are mounted inside the
state of the art OS-Truss mechanics used in all the OS open tube architecture telescopes. The same mechanics approved and used from worldwide research institutes for professional studies.

The RiDK 305 is 100% Made in Italy. Optics are made in Occhiobello Plant under the strict quality control of Massimo Riccardi.

The mechanics, designed by our R&D Manager, Giovanni Dal Lago, are engineered,
manufactured and assembled at the Thiene plant.

The RiDK 305 is the ultimate astroimaging telescope for whoever desires just the best in imaging all of the deep sky wonders in a beautiful, compact and superbly manufactured instrument.

The long back focus allows any type of accessories
to mounted, including cameras and rotators. It's the telescope for anybody who believes that imaging the Universe is one of the most important, serious and fullfilling experience for all night sky lovers and for for those who believe that image perfection is the minimum to which to aspire.

The Falco is an 80mm dual guidescope and finderscope.

It features a high quality 80mm Doublet with a focal length of 310mm.

Mechanical quality and finish is typical Officina Stellare quality.

The Falco is provided with a 1.25" Micrometric focuser and is ideal as a finder/Guider for the Veloce RH200.

The Officina Stellare Ultra CRC 300 ST telescope is a premier design. An ultra corrected Ritchey Chrètien telescope that features a unique and innovative primary cell design that includes a three fan ventilation system. Its beautiful zero expansion carbon fiber open truss tube body is trimmed with CNC aluminum fittings.

Each telescope is offered with it's own interferometry report stating and certifying the overall quality to the customer. In the making of the optics, Officina Stellare only use blanks of certified origin and perfect homogeneity. They offer, as a standard, very high reflectivity protected aluminizings and multi layer anti reflex coatings.

There is an in house, pneumatically insulated, 6 meters long and 500 Kg weight optical bench using a Zygo mark IV interferometer with phase shifter coupled with a highly sophisticated analysis software for producing extremely precise measurements and tests. Officina Stellare verifies each and every one of their instruments before delivery to the final user.

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.

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 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 Officina Stellare Veloce RH 200 - Riccardi-Honders Astrograph is a premier, innovative, Officina Stellare exclusive!

The primary Mangin mirror optical design features a large front full aperture corrector lens and near zero expansion BK7 optical glass for the primary and secondary mirror. It has two spaced elements for the rear group. The aperture is 200mm (8") and provides an incredible ultra fast, wide field with an F/3 focal ratio and 600mm focal length.

Add to that a flat 60 mm diameter field, with 6 micron maximum star spot size.

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 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 border 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 complete protection from stray light.

Inside the light shields there are also micro baffles that reduce internal reflections, coupled with an opaque painting of the surfaces, to nearly zero any possibility of stray light.

The back plate of the 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 Veloce RH 200 ships with the new Officina Stellare Focuser.

Officina Stellare decided to develop a special focuser which includes important features such as
large diameter, very low profile, micrometrical movement, Ability to motorise, easy interface with a lot of photo accessories.

The focuser has approx 16 mm of travel, a 72 mm x 1 (Takahashi standard thread) at the back end,

The focuser is guided by an external micrometrical screw (absolutely zero shift, the thread lockes the draw tube), and it is very strong thanks to the three Guide ball bearings.
