Officina Stellare RiDK

An evolution of the Dall-Kirkham design, the RiDK is probably the most "universal" family in our catalog, and the most affordable. With a f/7 native focal ratio, the RiDK (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, created this new family of telescopes. with superior performance and image quality.

The results are simply amazing: a telescope that 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.
