DESCRIPTION

Takahashi EM-400 Temma II Equatorial Mount

The Takahashi EM-400 Temma II mount has been developed to fill the gap between the Tak NJP and EM-500 mount. It has been designed to carry an 85-pound load. The EM-400 disassembles into three sections: The R.A./Dec assembly, the base assembly, and the counterweight shaft. This reduces the heaviest part to 49-pounds (22.3 kg), which is lighter than the weight of the NJP equatorial head. This makes transportation and set-up easier.

The entire mount rotates 360-degrees on its base for easier set-up, and allows the tripod to be set in the most secure position. All of the cables attach to the underside of the Declination housing and the use of internal encoders allows the mount to be used without having the cable wrap around in inconvenient positions. The 8 kg counterweights use two lock screws for more secure attachment to the counterweight shaft.

The Takahashi EM400 Temma II Mount uses the highly accurate EM-200 computing reticle with an 11x eyepiece to allow three arc minute polar alignment to the celestial pole. This reticle is usable until the year 2040. The EM 400 is a dual-voltage mount that will operate on either 12 Volts (500x sidereal) or 24 Volts (500x sidereal). The Temma II system is compatible with The Sky and other popular software using the free ASCOM and Linux drivers. This mount can be used anywhere in the world with a latitude adjustment from 0 to 50-degrees in either hemisphere.
