My observatory: First step, base of the mount

I started to plan fixed observing site last winter because I got tired of carrying things outside and back in. It happened more than ten times that I carry everything to my backyard and built them up and then when it was time to put power on the clouds came in and covered the sky. And the next thing to do was carry everything back in to the storage.

I started to plan this "observatory" at summer and soon decided to make it with roll-off roof. I also wanted to keep up the possibility to remove it during summer times. So the only permanent structure was going to be the base of the mount.

And finally at the end of September I started this project. Here is the base of the mount! 1 meter long tube with 55cm diameter dug in the ground and filled with concrete. (upper steel plate is there just to keep those 18mm metal bars straight...)
