- Start with dry optics: Wipe lenses and mirrors gently with a microfiber cloth before setup.
- Use dew heaters: Wrap strap-style heaters around your telescope’s corrector plate or camera lens.
- Insulate your equipment: Add sleeves or covers to slow cooling and delay dew formation.
- Choose your location wisely: Avoid low spots where cold, moist air settles.
- Monitor conditions: Use a hygrometer or weather app to track humidity and dew point in real-time.
- Improve airflow: Use a small fan to reduce local humidity around your gear.
- Check optics regularly: Inspect for early dew and adjust heaters or airflow as needed.
