When I first got into imaging, I thought I would need a dew strap and bought one. Dew is rarely a problem in west central Texas. I never used it. But, we have had way more rain than normal and I find dew forming or even frost the last couple of imaging runs. We are getting very near the dew point several nights and frost has been forming all over my place.
The dew strap I bought used has no control for the level. Will these work just plugged into a 12v system? I won't need it often so I don't want to spend a lot on a controller. Would a potentiometer work? Is there another way to control dew? I have a dew shield but it doesn't do much good when pointed up towards the meridian.
I know many people have to fight dew and have experience with this. I hoped it would just dry out enough out here to get back to our normal, dry conditions. But, I guess I need to figure this out....
