Will take a long time to equilibrate with the ambient air temp at night I expect so the structure will generate a plume of unsteady turbulent air that you need to view through. Did you take this into account ?

Hi Ian,
I appreciate upir concerns bnut the building is not concrete. Is is build with brick which has a completely different mass as concrete.
Here you can see the whole building progress

I painted it white in order to have as low as possible heating.
The cold room has 6 ventilation holes in the bottom each 6" diameter and the lower part of the cold room ege. where you can see both piers does not get any Sun in Winter when we have here the best onserving season.
Each pier has a mass of 6,000kg and I guess that is also a good source of lower temperature against the ambient. I have in each pier 2 holes into which I will put a temperature sensor in order to find out how the temperature of the piers evolve with the time.
Yes I did take your concerns into account as there is another astronomer here in Mexico who build his Observatory in a similar way and he has not reported any trouble with the heat generated by his walls and yes he has concrete block walls ando no vents like I did.His Observatory is sitting on top of a water reservoir.
I did take into consideration what you wrote and I said to myself. Better to use in such environment my telescopes as often as I can instead of waiting and having then collecting dust and waiting to go out maybe 2 -3 times a year to a dark site.
I am setting up the equipment and I will see what comes out. As last remedy I can specialize in Moon and Planet imaging which is a lot fo fun too ...
I am working also at the moment to be able to control the observatory remote from where I live.
Anyway I appreciate you having mentioned that posible risk I have and yes as I said I am aware of the possibilities ...
The best telescope one has is the one you use most often.
