This kit offers motorising and upgrade of the PORTA mount, driving in EQUATORIAL motions for astronomers with slewing up to 3 deg/sec. Tracking is maintained within 0.002 arc seconds per second of the correct rates on both axes up to 89.75 degrees altitude. It is most impressive in operation! Adapter plates easily fit onto the mount to which are attached the motor brackets. Substantial brass gears transfer the motion to the slow motion axes. The Azimuth plate has holes for spare eyepieces and the Intelligent Handset. By microstepping the motor assemblies (64 per step) there is almost freedom from vibration with the very small steps and a huge dynamic speed range is available. The gearing offers considerable torque to the slow motion axes. GOTO features on the handset include telescope co-ordinate readout (RA and DEC), entry of new co-ordinates, backlash correction, Periodic Error Calibration etc. Computer connection (optional) allows access to object databases. Motor brackets, gears etc have been designed and selected by ourselves to get the optimum speed / power out of the complete system. The metalwork is anodised Aluminium 6mm thickness to avoid going out of alignment.

The other specifications, features, capabilities and connectivity of the Intelligent Handset and the Microstep Drive Box is given fully or shortform. For further information contact Alan Buckman tel 01304 365918.

The drive performs at full rated load specification.
