Seems to be a simple "common" problem. I'm also in the process of buying a Pegasus Power box and a dew strap, so with all the activities I listed earlier and the dew strip, I'm hoping I'll eliminate this glow entirely.

The sky sucks heat. Anything exposed will soon end up with a lower temperature than ambient and will dew up more or less quicker depending on material and air humidity. That's why we wear beanies. Once you're dewed up you can't do much about it. But you can delay it by mitigating early evening into the night. Via insulation, applying heat, ventilation. Depends on your power situation, telescope design, and imaging site. Find something that works for you that is repeatable and stick to it. Make it part of your pre-imaging routine. Then you can cross that one out of the list and move on to the next looming issue.
