My new observatory is now well advanced.

It is 5 x 3 metres with a side room of 1.5 x 2 metres for the computers.
It also means I can insect screen this control room for summer.

Treated pine frame with 3mm thick gal L brackets from Bunnings and 45mm roofing screws to lock everything together.

100mm C purlin for the roll off roof track.

I used Aircell Insulbreak for insulation, nice and clean, easy to use and cut and no toxic fibres.

I am using curved .6mm curving grade colorbond corrugated roof sheets.

I will fix these to something like 100 x 40mm 3mm thick steel square section. I will bolt wheels to this steel first and they sit inside the C purlin which is standing upright and the C facing in towards the observatory.

I intend installing a solar powered air vent.

I plan on insulating under the roof sheets with the insulbreak and using this double sided tape I found at the hardware store to hold it up.

2 slabs. One is 2m x 2m as a pad and is 140mm thick with reo for a portable tripod. The other is 1 x 1 metre and 1 metre deep with lots
of reo in it. That is for a permanent pier and Paramount ME mount.

About a weeks worth of work or less to finish it off.

Floor is road base 100mm and then sand and then pavers. There isn't much area to do.

A single solid door for entry.

I'll post some photos.

Greg.
