The Best Times for Stargazing in Ahuimanu

Expert Tips for Ahuimanu Observers
Don't underestimate the power of peripheral vision (averted vision). At sites near Ahuimanu, looking slightly to the side of a faint nebula will reveal much more detail than looking directly at it, especially when dealing with the Class 5+ suburban skies of the HI region. Scientific Context: While local conditions vary, the instrumented reading of Bortle 3 at Pu'u'ula'ula (Red Hill) (114.0 miles away) remains the benchmark for regional sky quality.

Local Relevance
For observers in Ahuimanu, Pu'u'ula'ula (Red Hill) serves as the definitive baseline for high-altitude transparency and localized skyglow data.
"Similar sky conditions to the previous night with even more visitors staying for the sunset. Wind chill by the middle of the night in the 20's! Collected 6 sets with only 10 minute delay to maximize opportunities and then had time for 2 more before moonrise. Lights in the valley below were occassionally obscured by clouds, so most sets will have variations in light glow to the west. the lookout shelter on the summit is visible to the south and the observatories at "Science City" are visible to the WSW."
Pu'u'ula'ula (Red Hill)
Haleakala NP
Local Relevance
For observers in Ahuimanu, Pu'u'ula'ula (Red Hill) serves as the definitive baseline for high-altitude transparency and localized skyglow data.
"Set up equipment on the low ridge north of the parking lot for the summit viewing shelter. Considerable amount of visitors in this location before and during sunset. A few people with telescopes stayed until 11:00 p.m. Occassional headlights and flashlights interfered with data collection. The city lights of Kahului down to the SW coast (Kihie and Wailea) produced a substantial glow below the horizon. the Milky Way was rich i detail and the Southern Cross (Crux) was clearly visible. Extinction was moderate to the east and there were always clouds viewable along or below the horizon."
