I made up some covers out of insulation material which is about eighth of an inch foam "rubber" doubled it up so both sides are the foil side out. Stuck together with insulation tape.
I have tried many things including a beach umbrella over various covers but this is the best by far mainly because during the heat of the day your gear does not get cooked. That was when things were outside but I still put on these covers even though the gear in now housed in an observatory.
And I recently purchased a small windscreen fan/heater that runs on 12 volts that was to manage dew until my dew strip arrives hopefully tomorrow, or the one after that...it worked to manage the dew ok but after I put the foil cover over, which is tent like, I left the little heater fan running to reduce the moisture on the gear..From Auto Barn $45 ..The insulation stuff is at Bunnings and $50 buys heaps of it..I may make a cover for the scope and camera to keep dew off while in opperation.
