Are Dew Heaters Required in the Tropics

Here is the place to talk about all those equipment(Telescope, Mounts, Eyepieces, etc...) you have. Not sure which scope/eyepiece is best for you? Trash it out here!

Are Dew Heaters Required in the Tropics

Post by joecool1211 »

Just wondering if, in your experience, dew heaters are required to use scopes in the tropics? Or would dew shields suffice?

I'm thinking along the lines of refractors, SCTs, and Mak-Newts (tubes with a piece of glass exposed at the front).

Thanks!

You will need them sometime after midnight, especially if there is no wind. Dew tends to form anytime from then till dawn.
