Day 3 of new observatory

I had to wait for the wind to die down to allow me to manhandle the sides of the observatory which delayed my start until about midday. You know what they say about englishmen and the noon day sun -although I was born in Scotland!  The temperature was in the mid 30's,  as it is every day, and insects were homing in on me. I applied the insect repellent but obviously missed a few areas so I am writing this with bites on my ears, face and elbow! I managed to put the basic structure together but am waiting until tomorrow to sort out the motorised roof. 

Here is the sequence of the structure going up.
