    Officina Stellare RiDK 500 Astrograph

    with 72mm Manual FineFocuser

    Officina Stellare is one of today's leaders in the production of high quality astronomy equipment for the discerning professional or advanced amateur. Their products can be found in observatories around the world, and their high speed tracking lens systems are a relied upon component in the industries of aerospace and defense.

    The RiDK 500 (Riccardi Dall-Kirkham) represents the new reference point for all modified Dall-Kirkham instruments available on the market today. Massimo Riccardi, Chief Optical Designer at Officina Stellare, has the unique experience and creativity required to imagine and build a 500mm astrograph of superior performance and resulting image quality. The RiDK 500 is a system that delivers an 80mm fully corrected, flat field and an imaging performance that is diffraction limited across the entire field over a wide spectral range (380nm to 2000nm). These outstanding optics are mounted inside a state-of-the art Officina Stellare open truss tube made of carbon fiber and aluminum; the same high quality optical tube assembly used in all Officina Stellare open truss-style telescopes the world over.

    The Officina Stellare RiDK 500 is manufactured from start to finish in Italy. The optics are made in the Occhiobello Plant under the strict quality control of Massimo Riccardi, Officina's own optical designer. The mechanics of the telescope were designed by Giovanni Dal Lago, and are engineered, manufactured and assembled at the Thiene plant.

    The OS RiDK 500 is the ultimate astro-imaging telescope for anyone who desires the best equipment when it comes to the imaging of deep sky wonders. It is a beautiful, compact and perfectly manufactured optical instrument, and the long back focus allows the mounting of rotators, cameras, filter wheels, and other imaging accessories.

    The RiDK 500mm comes with a 7" dovetail and a Losmandy D-series dovetail is included on top for accessories. Three ventilation fans are part of the design, which helps the telescope reach ambient temperature as quickly as possible.
