- STEP 4. Observation Density: There are 5 recognized sites near Bloomington offering varied horizons and atmospheric stability levels.
Bloomington is positioned in a strategic 'Starlight Corridor.' It is far enough from the CA metro glare to allow for deep-sky imaging, yet serves as a convenient staging area for the deeper Class 7 skies found at Fifth street Lakeview.
The Best Times for Stargazing in Bloomington
While Winter offers the most consistent clear nights for Bloomington, wait for the 4-day window surrounding the New Moon each month for the deepest contrast. Since the sun sets early in the late Winter months, you can often begin deep-sky imaging as early as 7 PM.
Expert Tips for Bloomington Observers
When observing from High Desert Astronomical Society, try to position yourself facing away from the nearest major light dome. For Bloomington residents, this usually means looking toward the rural horizons of CA to capture the lowest magnitude stars that are normally invisible from the city center. Scientific Context: While local conditions vary, the instrumented reading of Bortle 7 at Fifth street Lakeview (23.2 miles away) remains the benchmark for regional sky quality.
