Officina Stellare RiDK 330 F/7
The Officina Stellare RiDK 330 F/7 offers a wide, flat focal plane (more than 65 mm in diameter, even in the smallest model!). A wide focal plane that is diffraction limited over a wide spectral range.
Since the corrector group is close to the focal plane, chromatic aberration is undetectable.
Almost everyone knows about the high level of innovation and technology that comes with any OS products, it’s clear at first sight.
Many knows that we’ve introduced new optical designs for nowdays demanding marketplace among amateurs and professionals, it is the base of our company, trying to be “smart” and one step beyond. So: we did it again!
Our challenge was to develop something different from a “Corrected RC”, with the same number of elements, the same pros (large corrected field, small spot size), but not the same cons (high cost and difficult to align). Is that possible? Yes, it is possible!
The answer is the new RiDK Range from Officina Stellare.
The RiDK Range (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 class astrograph of superior performance and image quality. The results are simply amazing: an optical system based on a spherical secondary mirror (then very easy to aling!) able to deliver minimum 70mm large corrected and flat field (depending from diameter) that with a polychromatic (range 400 to 750 nm) maximum 4 micron spot size at field edge! 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, designed to be thermal stable versus temperature change. The RiDK series 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 Sarcedo plant. The RiDK 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 believes that imaging the Universe is one of the most important, serious and fullfilling experience for all night sky’s lovers and for for those who believe that images perfection is the minimum to which to aspire.
