FOR SALE - Takahashi CN212 Newtonian Cassegrain Reflecting telescope
This is a unique scope – which comes with both a Cassegrain operation using a Cassegrain secondary.
Plus also a Newtonian operational capability, using a Newtonian seconday mirror. Thereby giving you two telescopes in one
You can change the secondary in a few short minutes to change the format to either a Cassegrain for visual or a fast Newtonian format for imaging.
This scope is one of a kind. It is also no longer manufactured
The optical principle of the CN-212 is simple yet clever. From a primary short focus parabolic mirror, pierced centrally, different optical configurations are possible depending on the secondary mirror placed in the light cone. Here we have two telescopes in one, an f/12.4 Cassegrain as the basic configuration, with a hyperbolic secondary mirror for high resolution work, or when you require, by simply replacing the secondary mirror and coupled with a low profile 2" eyepeice adaptor and associated field corrector, you transform your instrument into a brilliant wide field Newtonian with a focal ratio of f/3.9.
Excellent condition, I bought this telescope from Matt S (Kunama) nearly a year ago and straight after bought an Officina Stellare Supremo Mak 280mm - the world's best full Carbon tubed with Sitall optics and a Strehl of 0.99 Cass - this CN212 unit has been used once, it deserves a new home with someone that will actually use it. Matt takes exceptional care of his gear and this unit suits new buyer
