    Total Lunar Eclipse on 10 Dec 2011
    The above images were taken by the Observatory's staff with a telescope of 100 mm in diameter and 900 mm in focal length on the rooftop of the Centenary Building of the Observatory at various stages during the total lunar eclipse on 10 December 2011. During the eclipse, the shadow of the Earth gradually covered the moon and started to depart after Middle of the eclipse. During totality, as sunlight scattered or refracted by the Earth's atmosphere was projected onto the moon, the moon did not disappear but appeared coppery-red in colour although it was entirely inside the Earth's umbra.
