Fully refurbished rare Takahashi CN-212 Cassegrain Newtonian telescope complete with Vixen mount and upgraded Orion field tripod. This scope has had a full clean and service, visually tested and collimated.

This very unique scope comes with both an SCT secondary and a Newtonian one. You can change the secondary in minutes to change the format to either an SCT for visual or a fast newtonian format for imaging. This scope really is one of a kind.

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.

This rare scope features both an SCT format and a faster Newtonian format. This is acheived by changing the secondary mirror giving you a Newtonian f ratio of 3.9mm. Due to the fast f ratio, this is mainly used for imaging but can also be used visually with the correct eyepieces. Any higher than 15mm and you will need to use the supplied flattener to elimiate any curvature. We have supplied both adaptors to use the flattener visually and photographically. You will need a T Mount (not supplied) to attach your SLR camera to the scope.

The SCT format at the back has an f ratio of 12.4. Due to the slower ratio, this is mainly used visually. We have upgraded the rear to a high quality Moonlite dual speed crayford focuser to eliminate any image shift and to fine tune your focusing.

The scope also comes with a Takahashi SD-1 RA motor drive for tracking planetary objects. With this you can start imaging almost immediately.

The supplied 7 x 50 illuminated finderscope makes locating objects very easy. Very well made and fine reticles make it a very easy finder to use.

The mount is a Vixen Polaris but has the Orion giant field tripod for ultra stability. This will decrease movement caused by vibration.

Due to the compexity of the CN-212, it is aimed towards a more experienced astronomer that understands optics. It is in no way a beginners instrument. Please note due to the fragile nature of this scope, it is a collection item only. We cannot deliver this scope. 

If you have any questions or queries about this scope, please feel free to get in touch.
