I took 78 x 4-minute subs of comet Lulin on 28th February 2009 and created a deep-sky image of the object back then. But it has taken me until 10th February 2012 to edit all the individual subs into a short animation 🙂 Here you see comet Lulin moving through Leo and passing in front of a bunch of Leo galaxies towards the end of the animation. Enjoy 🙂
