Hi,

I had my collapsible Dobsonian telescope out tonight to have a look at Jupiter (more in another thread).

The conditions were still and a bit dewy. Dew started to form on the scope and covers. When I brought the scope back into a warm room the front lens on the finder scope fogged up.

At the moment, I have the OTA sitting on it's end, fully extended, pointing up with all covers off. This is to try to get rid of the condensation.

Did I do the right thing? It's probably too late now if I did. But if I did do the wrong thing, what is the best way to care for a telescope when bringing it in from the cold into a warm room?
