When you bring your telescope indoors after a cold night outside, condensation can form on lenses and mirrors if indoor humidity is too high. This moisture can damage coatings and optics over time.
Maintaining indoor relative humidity between 30% and 50% helps minimize this risk.
Tips to Manage Indoor Humidity
- Use a dehumidifier in your storage or workspace.
- Avoid rapid temperature changes by letting equipment acclimate gradually.
- Store gear in sealed cases with silica gel packs.
- Monitor indoor humidity with a reliable hygrometer.
Keeping indoor humidity in check protects your investment and ensures your telescope performs at its best.
