This deep image of Comet Lovejoy on December 23rd dramatically displays the color difference between the coma and the ion tail. Gerald Rhemann in Austria remotely operated a 12-inch f/3.6 astrograph in Namibia. This is a mosaic of two frames, each a composite of four black-and-white exposures totaling 18.3 minutes taken in different colors with a FLI ML 8300 CCD camera. - See more at: http://www.skyandtelescope.com/astronomy-news/observing-news/spot-comet-lovejoy-tonight-122920141/#sthash.l0mptRVt.dpuf

一般彗星轉彎會出現 ion tail , dust tail
如下面

目前 Lovejoy 尾巴是否兩個都出來?  不過有一說離子尾拍起會是藍的

好像 12/23~24 發生離子尾斷尾 . 所以 目前拍到很長的全都離子尾嗎?
 那塵埃尾是否不夠明顯?

1/9 晚上 位置

月亮 21:00 後會出來所以  要快點拍 .

Comet Lovejoy sketches from last night made using a 15-inch telescope. The coma is big – almost a half-degree across. The drawing shows the bright nuclear region and tiny “false nucleus”. At right, a suspected plume extends to the southwest of the false nucleus. Color is how the comet really looks in the telescope. South is up. Credit: Bob King
