Just a quick update, I've replaced the makeshift coreflute shadecover with a plywood shadecover and installed the solar panel and fan, just in time for summer. When I had the coreflute cover the mount was getting pretty warm (it was semi-transparent and let a lot of light through to the inner plastic container), whereas with the plywood cover the mount hardly gets warm even on very hot days (I really think it would get warmer if I left it in the house!). I make sure to wipe all the dew away after a viewing session before putting the covers back on and put a moisture absorber in the inner plastic cover to soak up any excess. All in all its working perfectly, I have absolutely no concerns about leaving the mount out all summer. The only thing remaining is the TARDIS makeover...
