The new EM-400 mount has been developed to fill in the gap between the NJP and larger EM-500 mount. This new mount has been designed to carry an 85 lb load. It disassembles into 3 sections, the R.A. Dec assembly, the base assembly and the counterweight shaft. This reduces the heaviest part to 49 lbs. lighter than the NJP equatorial head and makes transportation to remote sites easier.

The entire mount rotates 360° on its base for easier set up. This allows the tripod to be set in the most secure position.

All of the cables attach to the underside of the Dec. housing and the use of internal encoders allows the mount to be used without having the cable wrap around in inconvenient positions.

The 8 kg. counter weights (2) use two lock screws for more secure attachment to the counter weight shaft.

The EM-400 uses the highly accurate EM-200 computing reticle with an 11x eyepiece to allow 3 arc minute polar alignment to the celestial pole. This reticle is usable until the year 2040.

The EM-400 is a mount that operates on 12 volts.

The Temma-2M system is compatible with the Sky and other popular software using the free ASCOM and Linux drivers.

The EM-400 can be used anywhere in the world with a latitude adjustment from 0ƒAto 50ƒA in either hemisphere.

	Control panel and connectors The control panel and the connectors are placed above the mount. The encoders are located in end of worm gear shafts and are protected by screwed aluminum covers. The connector set includes both a power and an handbox pin, a RS-232 serial port and an autoguiding port (SBIG compatible). Controls include a power switch, a RA motor switch (standby), a power LED and a potentiometer to adjust the polar finder illumination intensity.
	The polar finder The EM-400 integrates the same type of polar reticle as the one used for EM-200 polar finder. An enlargement of 11x allows an alignment on the celestial pole with a precision better than 3 arcminutes. This reticle goes up to 2040. It is autonomous, as on the EM-200, and lit by an internal LED which is adjustable in brightness. The European version has an offset scale in longitude going from -10° to +10°. The calibration is carried out using a ring level. The simplicity and the speed of use of this polar finder are outstanding.
	Transportability and altitude wedge Two altitude wedges are available for the EM-400 mount, according to the latitude of the observer. The ML wedge version can be adjust from 0° to 50° of latitude. The standard model for European market, HL wedge version, is designed for latitudes going from 15° to 55°. The rotation of the wedge goes up to 360°. Three Allen screws, positioned with 120°, allow you to tight the wedge. For a better transportability, the mount can be dismounted in 2 parts ; the main block and the altitude wedge are assembled using 4 Allen screws. A screwable thrust secures the mounting unit perfectly and gives an irreproachable stability.
