The Best Times for Stargazing in Bostonia
Observation in Bostonia is most rewarding during the Summer months. During this time, the colder air masses over the Pacific region often result in significantly higher transparency, allowing you to see objects like the Andromeda Galaxy or Orion Nebula with much more definition.
Expert Tips for Bostonia Observers
If you're visiting Irvine Lake, bring a pack of chemical hand-warmers and rubber-band them to your eyepiece or camera lens. This acts as a 'budget' dew heater, which is essential for the humid nights often found in CA during the peak viewing seasons. Scientific Context: While local conditions vary, the instrumented reading of Bortle 5 at Palomar Observatory (37.0 miles away) remains the benchmark for regional sky quality.
