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 305mm 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 2000nm! 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&DManager, Giovanni Dal Lago, are engineered, manufactured and assembled at the Thiene plant.
