- Confusing dew with humidity: High humidity doesn’t always mean dew will form, but ignoring dew point temperature can lead to surprises.
- Skipping dew point checks: Not monitoring dew point forecasts means missing early warnings for condensation risk.
- Overusing dew heaters: Running heaters at full power all night wastes battery and can cause image distortion.
- Neglecting insulation: Cold surfaces attract dew faster—failing to use insulation wraps speeds up condensation.
- Dirty optics: Dew clings more to oily or dusty lenses, so clean your gear before every session.
By avoiding these errors, you’ll protect your equipment and improve your astrophotography results.
