EM-500 Temma-2 equatorial Mount
It's true, this amazing mount looks like a large EM-200 but the size is just impressive. It releases an immediate feeling of stability and refinement. Its design points out the EM-200 but it is much more than a simple oversizing.
In spite of its weight of 45 kg, the EM-500 EQ mount will not be restricted to an only observatory use. Indeed, it is installed quickly on its stand pier and will be polar-aligned in a few minutes only using its integrated and precise polar finder. With a maximum loading capacity of 45 kg, it will be able to receive large-sized tubes, such as Mewlon-300 or the BRC-250 reflectors.
The EM-500 becomes a fabulous and final tool for the demanding amateur astronomer who will consider his transport for a temporary use in altitude for example.
Features:
The fully integrated motor drives ensures a reliable and precise control of tracking and slewing speeds for astrophotographic or CCD guiding. The electronic control panel allows speed adjustments of slewing corrections by increment of 0.1x sidereal rate on both axes. A connector is available for autoguiding (SBIG compatible) as well as a RS-232 serial port
The tracking accuracy is announced with an error of ± 3.5 arcsecond per turn of 10 minutes worm gear shaft (without guiding system).
The mount is delivered with the same handbox that equips other Takahashi mounts. It is provided with R.A. and DEC. rotation reversers as well as a switch for slow (green LED) and fast 100x (red LED) speeds.
The EM-500 EQ mount is equipped with Temma-2 goto system. An automatic pointing of the celestial objects is possible when the mount is connected with a computer (with a serial cable, provided). The Pegasus 21 computer control software is provided too. The Temma-2 system is compatible with a large range of astronomical softwares (TheSky6 or Starry Night, for instance).
The EM-500 polar finder is equipped with a ring level which makes it possible to quickly calibrate the polar alignment reticle. The polar alignment is made by the means of a large altitude screw and with 2 azimuth screws. Once the Polaris position has been exactly determined (with graph or software), then the polar alignment takes only a few seconds, as it takes on smaller mounts.
The Temma-2 system includes two encoders located at the end of each axis and connected to the control panel by two cables.
