I am curiuos how you all that do extended timelapses at night deal with dew.  I acidentally left my Pocket 3 outside overnight and in the morning it was covered in condensation (water).  I also tried but failed on an all night timelapse with my Action 5 and in the morning the camera was also covered with 'water'.

What are your thoughts?

Thank you.

You can get a battery powered fan blowing over the lens, that can work in a pinch
