EM-400 Mount and Specific Accessories
Prices Technical Specifications
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 40 kg load.
This mount disassembles into three sections, the R.A. Dec assembly, the base assembly and the counter weight shaft. This reduces the heaviest part to 22.3kg which is lighter than the weight of 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 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 dual voltage mount that will operate on 12 volts [250x sidereal] or 24 volts [500x sidereal].
The Temma-2 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 0° to 50° in either hemisphere.
