Hi,

I may soon have the opportunity to house a telescope on the roof of a 3 story home in Northcote in Melbourne. The home has uninterrupted 360deg views of the sky that can never be built out. I'd love to house a scope there for imaging (light pollution notwithstanding). The problem is that there is no way to put a pillar in to the ground. The roof of the home is a tiled entertaining area, so I cant do much more than put the scope and a small roll off type cover. Vibration and movement from the house is the obvious problem. Does abyone have any suggestions for isolating/minimizing such movement? How to mount the pier? - I have a portable pier, and also an unused 10" diameter steel pier I could use - or perhaps a lightweight tripod on pads might be better? or do I need to start saving for some form of AO unit?

thanks for any suggestions,
cheers
Gary
