Hi All,
I built my observatory in early 2010 and so has now gone through a whole season and I'm happ to report that it has managed to cope with some really terrible weather over the past year and a half and is still going strong.
So I decided to post a link of how I built it in case some other DIY types wanted to see a some what different approach.
Here is a link to some photos.
