I recently acquired a 20-inch dobsonian and I am considering storing the scope fully assembled in a 6 x12 cargo trailer.
Question: I live in the Midwest with lots of hot/cold/humid weather. What precautions would I need to take to avoid condensation from forming on optics (e.g., as a result of warm humid air condensing on cold mirrors/lenses)?
What would I need to do to properly ventilate a cargo trailer for year round use as scope storage in a humid place like the Midwest?
Specific things I am considering:
- Insulate the trailer
- Monitor the temperature/humidity with a wireless internet connected thermometer/humidity sensor
- Operate a lightbulb or two in the trailer to keep the trailer above the dew point). Would this be enough during the winter?
- Operate a dehumidifier inside the trailer - especially during the summer
- Operate a fan continuously (to keep air moving and prevent dew from forming)
Is there anyone out there from the Midwest (or similarly humid place) who has successfully stored their scopes year round in a cargo trailer? What did you do to make it work?
