Dew Control in Observatory? new
      #6109007 - 09/30/13 10:23 AM

Do y'all use dew control strategies in an observatory? If so, what do you do (sorry, puns make me happy).

I use a normal dew controller that is wired into my roof controller. It has an automatic on mode that looks at the dew point and kicks it on. Works really good. We don't get a ton if dew here though.

Which brand of dew controller?

What about a dome?

I have a dew shield and dew heater on my telescope; my corrector doesn't dew up but on the really bad nights (last night) my primary (!) can. My observatory (dome) makes an otherwise impossible night not a total washout, but I know of no way to stop dew entirely. Everything in my observatory was wet last night, except the corrector (*chuckle*). After I shut down the dome my dehumidifier kicks on.

That's all I know I can do to combat dew.

It's some guys home built project. It's a little retro but it works just fine. Honest, any dew controller will work... Unless you live where Tori lives!

Yikes

I don't fortunateley. I live in the Land of Some Dry Winds and a Few Wet Ones
So I shouldn't have overly much trouble

I am asking because the last three nights were really wet (dewy). I am considering getting a dew controller.

Hi Steve:

There's different dew situations that need different strategies. Are you talking about your scope dewing up while observing? Or are you talking about the observatory itself getting covered with dew inside when you're not there?

Both. I ordered a dewbuster for the scope(s). But I am also concerned about electrical equipment and dew so I am looking at a dehumidifier for the observatory. But I don't know if that will solve the problem.

Sounds like you're covered. DewBuster for the scopes and dehumidifier for the observatory should do it.
