I'm not sure about using a boulder at the base of a pier. Could be a lot of hard work and nothing but problems. I would be worried about the two seperate components moving in the ground.
I opted for a concrete pier in my observatory. I dug a hole a lot larger and deeper than i required for the pier and filled it with concrete. Before the concrete set i pushed the pier cage into the concrete.
Once the concrete set i placed the pier shutter over the rebar cage and concreted the pier. The result was an 12" diameter pier that is attached to an extremely large chunk of concrete. In two years there has been no movement of the pier yet. The pier is isolated from the observatory and it causes me hardly any vibration problems either.
There are some plans of my pier design here:

I think your design might work well enough without the boulder. I also have concerns about the concrete adhering to the boulder and if they seperate the weight of all that concrete above might start some movement.
P.S. See what the guys at: http://tech.groups.y...lescopic_Piers/ have to say about your design. They are very knowledgeable when it comes to pier design.

Its not a commercial site. Its an enthusiast site where people can learn about observatories and see observatories that others have bought or built. There are photo galleries and illustrated building projects that I found really helpful when I built my observatory. All brands of domes, roll-offs and home-built observatories are talked about and everyone is welcome.
You can post photos of your observatory for others to see.

You can get all your information on the Explora Domes history and projects. Also get up to the minute manufacturer updates.
You can post photos there or view other built observatories all in one location.

Solar Power for observatories thread.
Marcus' response is full of important info. Putting a link here is as good as making a sticky of the thread.

Has anyone thought about using a 1000 gallon plastic fertilizer storage tank as an observatory? Any ideas let me know.
My neighbour and I had one. Our intent was to have a warm room, our scopes would still be outside. It had been cracked, so all we had to do was pick it up and take it away - for the cost of a flat of beer. We lined it with reflective material, used red rope lights and had shelves built almost all the way around. We kept a desktop computer inside, a small heater and two rolling chairs. Where the crack was, we made and framed a door. Outside, a few feet from the door, a permanent pier was installed. After it was done or before we started (I don't remember which) we gave some thought to having the scope inside, but couldn't come up with a viable plan to cut the top/bottom and still keep it weatherproof. It served our purpose that winter, allowing us to keep a lot warmer (no more ice in the moustache), have all our accessories close at hand and not have to cart everything back into the house. We eventually replaced it with a store bought observatory, and pushed/trucked the warm room across the street, to where it became a playhouse for some kids.
This was before the door was finished, and when we picked it up where you can see the crack.
The pipe coming through above the stars, was where the wires for the scope and camera came out.
It ended up with lattice around it so that it couldn't be seen from the deck.

This link shows the dome and the 42 being constructed: http://tinyurl.com/2ozsvc
If you are considering a similar project, I'll be happy to give you a tour.
