computer cupboard
Re the computer and monitor
My observatory is quite small so I decided to make a simple timber cupboard which is bolted to the wall. I think it is about 500mm deep 800mm wide and 900mm high and has a horizontal shelf spiltting it in to 2 equal halves. I have 2 rolladoors which I got from Ikea installed. The rolladoors are space efficient and keep the PC gear protected and shields stray light from the monitor to the scope. The top shelf is at eye height when sitting and has a wide screen LCD on a swing arm. The PC and keyboard sit in the shelf below - I use a compect PC to save space. My legs/chair can fit underneath.
I also run cabling up the pier and have 240v at the pier and on two walls - I used exterior grade powerpoints. Just prerun the 240v flex through conduit and get the electrician to finish it off.
As Brett suggests if you have solid rock, secure some reo into holes drillied into the fresh rock and form the concrete around these with a sticky mix - not going anywhere after that assuming the rock has good strength such as fresh Hawkesbury sandstone.
Putting a good sheet of sarking under your floor - in my case thick formply isolated from the pier - helps with further heat/pest shielding. I also lined the interior of my observatory with ply painted black - this is optional I guess.
