Im not worried about cooling lower than ambient. Most days are around 29 - 34 degrees in summer. If the temp stays this hot in the observatory then I amnot worried about equipment. Its when I see the temp inside edging 45 - 50 that i get worried.
The whole point of an observatory is to leave your gear setup so you can get observing or imaging quicker. If you pull your scopes and camera off each time you would in my case nearly an an hour setup each time to get scopes on, counterweights on. Cables conected to DSLR, SBIG, Robofocus, Optec TCF focuser, dew heaters etc..., Scope balanced, pointing model rebuilt etc.... Just too much hassle not to mention the chance of stuffing it up , so my goal is to get the temp to an acceptable level.
I guess I could buy one of those Portable humidifier type airconditioners for summer and let it run. Power bill will be huge, but hey the scopes will be happy.
I think I will paint the roof white for starters, add some more ventilation top and botton, Add a couple of bathroom style exhaust fans up hig on the wall on either side and see how I go. Next stop after that is foam.... I Cant paint whole shed white as wife will object...
Best Regards
Chris
