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 now days demanding marketplace among amateurs and professionals, it is the base of our company, trying to be "smart" and one step beyond.

Many of our customers are asking us why we don't have a Dall-Kirkham or a CDK telescope between our arsenal of products, well that's because of our 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, we always try to get 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 60mm large corrected and flat field that is over the diffraction limit on the entire field and, more than this, over a spectra 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 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.


The review Di Cicco's conclusions is:
"I’ve tested a lot of equipment over the years, but I can’t recall ever having a better experience than I had with the RiDK 300 and Paramount ME II. And given the sophistication of this setup, that says a lot. It truly is exceptional stuff"
