I hate this!  I can't really help what happens to a telescope that is in use too much, but all my crap in the observatory doesn't need to be out under the night sky when I image can be somewhere else.  Besides my efforts to put all electronics "under glass" with cooling, I want to move almost everything else into a companion shed that I am going to build under where the roof rolls off to. I'm thinking a 10x8 shed, but I am still designing it. Being about a mile and a half from the Deleware River I top 90% humidity almost every night.  The lowest humidity I've seen in months was about 65%.
