Well, looks like that I am not as unhappy as I thought
Well, I took some days off to install the equipment. Here a few images of how it looks now with some equipment as well as a lot of unsorted stuff everywhere
Entering the cold room
Inside view from warm room to cold room
View of the 2 piers with the G11 mounts and 4 Takahashi telescopes
Mewlon 250 + FS-78
TOA 130 + Sky 90
Open Roll Off Roof
Roof half open or half closed :-)
Thanks for looking.
Taking reference to the long posting of Ian in regard to thermal currents I have been doing some temperature measurements at the inside and outside of the walls and it does not look that critical as I read in Ians posting.
Anyhow I am happy now that I can use again my telescopes after nearly 2 years of doing nothing eg. making test from the inside of my appartment in Mexico City.
