Pier for in the roof observatory

I am having an observatory(home dome or prodome 0 builtinto the roof of a 2 story house. Dies any one have any ideas on pier support in the ceiling of the secondfloor room ( floor of observatory.) The height is too great for a metal pipe in concrete.) I have a 10inch Meade SCT and hope to do some astrophotography as well as direct viewing. Gwen

I think you will have to extend your pier(metal or concrete)into the ground. Otherwise you will see a great deal of vibration at the camera.

Good Luck with your project! 8) 8)

Gwendoline,

I will second what Andy has just posted. Without me turning this into a long winded post let me just say "been there...done that".

You would need to construct a completely isolated steel or concrete frame to dampen the vibes transmitted from people walking in your home while you are observing.

I have since moved my observatory to the back yard.

I am only assuming that you have an "American" (wood framed) home. I have some European friends that laugh at our wooden houses here in the USA
