Yet another pier thread. How deep for a CGEM?

I want to build a permanent pier for my CGEM. It will need to cope with the weight of a Meade 12inch ACF

How deep and wide a hole do I need? I was going to use a star post hammered into the centre of the dug hole, and then a PVC piping around he post to hold some concrete.

Edit: This is the sort of thing I was considering:
