Comet ISON is currently in our inner solar system when i shot this image and it will make its closest approach to the Sun on 28 November 2013, making Comet ISON a sungrazing comet. Comets are notoriously unpredictable and so, nobody can be sure if it will survive its close pass to the Sun.
Red comet tails are caused by the light of the Sun reflected from dust. The thickest part of the dust tail is beneath other layers of dust and that reddens the reflected light much like the Sun turns reddish when it is on the horizon and the light has to pass through more of the atmosphere.
