Takahashi EM200 & Takahashi CN212
Hi all!
I have for sale a mint Takahashi EM200 Temma 2 Jr.
I'm upgrading to a beefier mount and this one has to go! Absolutely perfect conditions and a wonderful mount! I would not sell it if my setup would not be so heavy!
I can pay for 30% shipping to Australia, you pay the other 70%! Paypal please add 3%. If paying by echeck via Paypal there are no fees but will wait for the echeck to clear!
----------------- >>>>>ON HOLD!
Takahashi EM200 Temma 2 Jr.
Takahashi Mahogany Tripod
BT Tech Saddle plate
2 x 11 lbs Takahashi counterweights
2 x 11 lbs Atlas Eq-G counterweights (new never used, still in box)
12-24v converter from Chuck Faranda
Pelican 1650 case
Cables, manuals, certificate of inspection
Please visit my website and check out the images. They were taken with this mount.
Also, I decided to sell definitely sell my mint Takahashi CN212 Cassagrian/Newtonian.
The CN-212 is two, two, two telescopes in one!
Choose either a f/12.2 Cassegrain or f/3.9 Newtonian configuration.
Includes 7X50 finder, Newtonian assembly with photographic corrector, and collimation tools.
The idea of combining the advantages of Cassegrain and Newtonian configurations in one instrument has been around for a long time but with very few examples commercially available.
Thus it was not so much a novelty of telescope optics, but rather the result of a long held need for the ideal all-round telescope for the amateur that gave birth to the Takahashi CN-212.
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.
