Like all TAKAHASHI mounts, the EM-200 Temma-2M is a beautiful, high-precision, very-solid GOTO mount, which is designed and built to last a lifetime! It is no wonder, that the world's top Astrophotographer; Rogelio Bernal Andreo, uses the TAKAHASHI EM-200!
The EM-200 provides a stable support for all types of instrument (refractor, reflector or cassegrain) weighing up to 18kg. The modern aesthetic design of the EM-200 is highly attractive as well as beautifully functional. The RA and DEC stepper motors are fully integrated into the mounting, the high precision design and construction provides cyclic errors lower than +/- 5 arc seconds.

The integrated polar alignment telescope has an illuminated reticule which can be dimmed to suit the user or observing conditions. This in conjunction with the precision altitude and azimuth adjusters will typically give polar alignment accuracy within 2 minutes of arc of the celestial pole.

With a function-full hand controller, options on tripods and piers and also optional digital setting circles the EM-200 is an ideal mounting for the serious amateur.

The mount can operate in Temma mode and in the normal mode using the hand control.

The Temma requires the use of a PC to operate.
