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 lb. 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 lbs (22.3kgs), 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 it's 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 Dec. housing and the use of internal encoders allows the mount to be used without having the cable wrap around in inconvenient positions.

If interested call 800-483-6287 and ask for Rod or Sean. Thank you for looking.
