I have a Celestron SkyQ Link for sale which will permit most Celestron electronic mounts to be remotely controlled by an iPad or other device.
Costs $200 but will sell for $90. I am in the Perth northern suburbs so if you can't pick it up the buyer will have to pay shipping - it wont be much though as it's small.
