Comet PanStarrs in the norther sky

    Comet PanStarrs, which has swiftly moved from the southern hemisphere to the northern hemisphere, is now shining in the northern sky and just about to become a circum-polar comet visible all night.
    This photograph was taken around half past three in the morning on April 11, when the comet was still relatively bright showing its majestic tail. It is at magnitude 5.5 and faintly visible to the naked-eye. Great comets often shine hugging the horizon, which makes it difficult to see with the naked-eye. The reddish color of the comet in the photograph is perhaps caused by the atmosphere low on the horizon.

5-minute exposure at 3:33 am on April 11, 2013 (J.S.T.)
70cm f/7 reflector with ISO 600 film
