Hi,
I recently installed a pier in my garden, with the intention of leaving my EQ8 on it all the time and just bringing it my scope and camera, so I fitted it all, and had a waterproof breathable cover made to measure, and after a few days it was all good, then a few days later it was drenched in condensation and I thought I had ruined my mount... ๐ฎ, I have no idea why this happened, as many people, example above just throw a cover over and all is good ๐ค, so anyway after trawling the Internet, I read a post somewhere that said a breathable cover is not always a good idea and to use a telegizmo 365, which are NOT breathable but have the silver lining to stop heat build up and also to secure it well around the bottom with a large desiccant pack inside to remove any moisture....and this has been superb, not a drop of moisture, and the desiccant packs are re chargeable by plugging in the mains for 12 hours, and last for ages in such a small space... I reckon I could leave my scopes on too....
So thatโs what worked for me, the problem with condensation is that it can come and go in a few days, so unless you check under the cover almost every day, you might not even know it was there until itโs too late and electronics are ruined....
HTH
