Title: 22° Sun Halo
Post by: Rainer SLP on June 02, 2015, 07:04:42 pm

Hi,

I hope it is OK to put this here even having many buildings around the natures spectacle.

Testing the Canon EF 8-15mm f4L Fish Eye zoom.

What you see between 4 and 5 o'clock is my Astronomical Observatory with a warm and cold room.

Nice! Warm and cold rooms - why? I'd figure you would want scope and its housing at ambient all the time, maybe with a dew-heater on the business end

We call the warm room where one sits and the cold room where the telescopes are. If you look carefully you can see a 2 water shaped roof. That one I move to the left over the warm room and open where the telescopes are and that is what we call the cold room  ;D

That Observatory is located in central Mexico, city of San Luis Potosi in the state of San Luis Potosi, where the climate os semi desert like and I have never needed the dew heaters. Also maybe due to the fact of the 4 walls around the scopes.
