Maybe this isnt such a good idea. It seemed ok when i first thought of it
as
i have a lot of trees nearby and being up at that level would have given
me
access to lower areas of the horizon, plus a short run from there to my
computer room would have let me do some imaging to my desktop. The
proposed
location of the platform actually would have had a straight shot down to
the ground so i suppose it could be Beam supported right off a concrete
pad
below. If i supported the platform with 6x6 wood stilts sitting on a
concrete pad and braced to the side of the house would vibration still be
a
problem?

You could probably save on cost, and hassle, if you built a small
observatory as a seperate building in the yard. You could avoid the temp
problems of the roof, and being on the ground, you could pour a nice solid
pillar. Trench out to it, and you can have all the computer hookups that you
could wish for.

I am hoping to do this in my yard some day. Still working on spousal
approval. I am hoping we can some day replace the old decrepit shed with a
larger model, with a sliding roof, and room for my scope next to the shovels
and mower.
