Product Details

  • Takahashi EM-500 Temma II Equatorial Mount

    The state-of-the-art Takahashi EM-500 Temma II mount has a tracking accuracy that is guaranteed to +/- 3.5 arc seconds without periodic error correction and it runs off of 24V DC. The EM-500 Temma II slews at 560X the Sidereal rate. The Temma II GoTo System can be operated via The Sky, Level IV software (and more) and is closed-loop. This means that the telescope can be moved manually without restarting the GoTo system. The mount can also be operated in manual (non-GoTo) mode without connecting to a computer and dual-axis tracking is available in this mode.

    The self-contained illuminated polar finder is accurate to two arc minutes of the pole. Autoguider and CCD cables are available for most CCD cameras including serial, RJ-11, and USB connectors. Main gears are phosphor-bronze with matching poly-steel worms for greater accuracy and durability vs. aluminum & stainless steel. New, precision micro-stepping motors provide high durabilty with softer pulse-peaks for better imaging. No need for servos and variable-voltage systems that reduce longevity.

    Despite being observatory quality, there's no need to hide the Takahashi EM-500 Temma II indoors. It can be easily installed on a portable pier and polar aligned in just minutes thanks to the intergrated polar finder, easy balance and precision of this system. This rock solid mount is capable of taking on large OTAs and your most demanding astrophotography applications!
