Takahashi EM-200 Temma 2Z Computerized GoTo Mount - High Latitude

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.

Includes TWO 5.0 Kg counterweights (p/n TCW0230) and counterweight shaft plus a full set of cables.

Customer Reviews:

This mount is an outstanding machine. No more drift aligning as the super accurate polar scope is correctly aligned out of the box - I get no drift at 300x after a quick (but careful alignment and I'm ready to image even before it's really dark enough. Tracking is excellent and the mount guides very well. I measured 7 arc seconds peak to peak PE on my mount. I'm getting photos that I'm very happy with now after struggling with a lesser mount. My goto's are very good on the same side of the meridian but they are off a little when crossing the meridian. Not a big deal since I primarily image with the mount and the very quick one star alignment after a meridian flip is really no big deal - literally takes two minutes and hit sync on your planetarium program. Also, thought the lack of a real handset (e.g. autostar, nexstar would bug me but it does not at all. I use a small netbook computer and it's great - actually prefer it now even when using it for visual. This is a very fine mount. The Astro-Physics mounts probably have even better tracking with PEC but I don't plan to buy one as the A-P mounts don't have the Tak polar scope which I just love because of the time savings in getting a very precise polar alignment. You can't go wrong with this mount. Looks great too with the paint color and wooden legs. I've used mine for 6 months before posting the review.

This is the medium level mount that is a total joy to use. It's PEC is extremely low in error giving you excellent guiding with a fair amount of weight. Like all Takahashi mounts they are precision engineered from the ground up and the quality shows it. Truely a remarkable mount but owner should know that it does require a PC in the field to operate the go-to system. There is also a new hand controller in the form of an HP Pocket PC.
