Takahashi EM-11 Temma 3 Mount with Power and Controller on Sale

Takahashi EM-11 Temma 3 Mount with Power and Controller

The Takahashi EM-11 Temma 3 equatorial mount is a German equatorial “GOTO” mount designed for loads up to 18.7 pounds. Designed for use in latitudes between 20 and 50 degrees, this superb mount has a look and feel that one expects from a Takahashi product. The mount features 144 tooth worm gears on both the right ascension and declination axis for precise slewing and tracking.

The EM-11 3 operates off 10.5 – 24 VDC and is capable of GOTO operation from a PC or Mac, with both medium and high-speed slew rates of up to 350X, and slower manual slew rates for R.A. and Dec. adjustments. Connection to the computer can be through a USB connection, an RS-232C connection, or using the built-in Wifi capability. 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 equipped with manual scales for both right ascension and declination, graduated at 10 minutes and 2 degrees, respectively.
