GP-DX mount showing motors in situ

This kit allows operation of the Super Polaris / Great Polaris type mount up to 3 deg/sec for fast slewing. It is most impressive in operation. The motor brackets fit where the original motors fit and substantial gears transfer the motion to the slow motion axes. 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 and hence considerably improved torque and smoothness in operation. GOTO features on the handset include telescope co-ordinate readout (RA and DEC), entry of new co-ordinates, backlash correction, Periodic Error Calibration etc. The kit is supplied with an on-board database so computer connection is optional but connects with standard planetarium programmes. Motors, brackets, gears etc have been designed and selected by ourselves to get a quality system that will last. It is substantial enough to withstand (mis)use and the major components can be transferred to your next mount.

All the comprehensive 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.

We often get asked how much load it will take. The best way to specifiy this is how much torque is present due to the telescope (or balance weight) on the DEC axis. Our demonstration 8 inch Catadioptric is on an EQ5 and needs 23.4 Newton metre from the balance weight (10kg at 23.4cm) and is equally balanced by the telescope. This feels comfortable and drives at full spec from this GOTO kit.
