Spent 4 nights last month fighting dew on my lens before I figured out the fix
Kept getting foggy shots of Orion from my yard in Boise. Tried wiping the lens, then a hair dryer on low, then wrapping my hoodie around the tube. Nothing worked past 20 mins. Finally a guy at the local club mentioned a simple dew heater strap for $35. One clear night after that, no fog at all. Anyone else learn a basic fix way later than they should have?

Wait, a hair dryer on low actually seemed like a decent idea to you at the time? That just blows warm wet air at the glass and makes the fog worse once it cools, which is probably why it never lasted past 20 mins. A $35 strap sounds about right for a fix that simple, and honestly most of us learn this stuff the hard way.
