That time of year again - Dew in observatory

[Merlin66]

Just a remindered....

For the past few years I've been using a "heated doggie blanket" - 1.2 x 1.2m , 12V about 80W as a dew protector - just drop it over the scope/ mount after the observing session to keep it dry and protected.

I also found the "heated throw over rugs" - 240V version of the above have a two hour time out which is pretty handy.
