Hi Clive,
Very, very interesting post. I have an Ostahowski's 16" 1,6" thick pyrex primary mirror and the problem is that my Dobson not acclimated enough to perform at their best. I have three 120 mm fans blowing air, two for the boundary layer and the other in the back of the mirror. Here, in my usual place of observation, the temperatures fall in winter about 9-10ºC in three or four hours. I saw my telescope this summer fully acclimated in a privileged observation area at 2000 meters altitude and the images were spectacular.
Is there any magic formula for to bring the mirror at his ideal temperature?
