The Takahashi EM-400 Temma 2Z mount is a highly accurate, superbly crafted German equatorial mount suitable for loads up to 77 lbs.  The mount features the Temma 2Z control system, allowing for PC GOTO funcionality as well as precise control using the supplied hand controller.

The EM-400 T2Z operates off 12 VDC and is capable of GOTO operation from a PC or Mac, with a high speed slew rate of 500X, and slower manual slew rates for R.A. and Dec. adjustments.  The mount features a built in, illuminated polar finder scope for accurate polar alignment, facilitating accurate tracking and GOTO's.  To further enhance tracking capability, the mount is autoguider capable.  The mount comes equiped with manual scales for both right accension and declination, graduated at 10 minutes and 2 degrees, respectively.  Two 17.6 lb counterweights are included.
