- Ignoring dew formation: Moisture can condense quickly, so always use dew heaters or shields.
- Skipping weather checks: Not monitoring humidity forecasts leads to unexpected fogging.
- Poor telescope ventilation: Lack of airflow traps moisture on optics.
- Neglecting equipment protection: Store gear in sealed, dry cases to avoid damage.
- Rapid temperature changes: These encourage condensation—acclimate gear slowly.
By avoiding these pitfalls, you’ll protect your gear and capture sharper images even on humid nights.
