Buena Vista Peak
Kings Canyon NP
"Site on summit of Buena Vista Peak, rocky outcrop on north side of the broad summit. Seeing very good, transparency good, hazy toward the valley. Few high clouds far west and southwest. Considerable glare from lights in the valley, must turn away or move away from the summit to block from view to keep night vision. Light dome from Fresno/Visalia extends to 45 degrees above the horizon, sky at zenith pretty dark, however, and easter sky quite dark. Airglow fairly strong."
Buena Vista Peak
Kings Canyon NP
"Slog through snow to reach summit, transparency good, seeing good. Light from Fresno/Visalia subdued by haze and fog in the valley. Sky at zenith pretty dark, zodiacal light faint above light domes to west, gegenschein barely seen near Jupiter. Looking to the northeast airglow very slight. Light domes fairly bright, degrade night vision, but turning away reveals an excellent sky. Two images on first data set not aligned, slightly darker because of instrument runaway, clouds to west in first data set reflect off light domes amplifying light pollution. Second data set excellent, only a small cloud remained over Fresno."
