Problem:Condensation has formed around the dust at the center of the dewar window when the humidity began rising. Humidity levels are still safe for observing, but too high for this particular setup. |
Fix:Fix depends on the observatory (possibilities include blowing dry nitrogen into the setup or heating the dewar window enough to keep the dewar window dry). |
