Worked OK: 2x stepper motors for azimuth and altitude, meccano gears, arduino sketch controlled the 360x180 sequence which was triggered by a cheap radio control off ebay.

Didn’t get around to photographing the stage in close up as I was against a deadline and I’ve now taken it apart since I’m now building a new improve head with:
More powerful stepper motors which can move the camera faster, use an encoder (from a junked printer) for feedback and xml generation, Arduino software library for micro-stepping, Xbee radios for real time 2-way communication (the rig is on 4 meter pole). I’ll let you know how I get on (should be ready in a couple of weeks) and I'll try to remember to take a few photos of the process.
