Condensation Control

[Boozlefoot]

Was running 40W light bulb on timer in obs for condensation control.......moths invaded and eventually burnout of filament. (Over time)

This unit has plugged into the existing digital timer - all good - placed on top of pier with BBQ cover over top - no moths - no risk of melting cover/skirt. All clear to roof of obs - overfow heat rises from skirt. 60w on timer frugal insurance.

I have used a shroud placed over my mount in the observatory for probably 8 years now. The CGX mount sits on a pier which goes through the floor into the earth, inside the shroud I run a low wattage incandescent bulb on a timer. The shroud itself is made out of foil builders bath material purchased from Bunnings, and has a small opening at the top to produce a convective flow which keeps the mount dry.
It takes me only about two minutes to remove the mount shroud when I am getting the observatory ready for use. This is a good winter setup. In summer I still use the shroud but without the bulb heater. No moths anywhere.

When I had my observatory i used to run a portable fan non stop on low, the circulating air would keep everything perfectly dry.

A fan running 24/7 would last me at least 6 months and at 15 bucks from Bunnings it was a great way to keep everything dry.

Just my two cents worth.
