Comet 103P/Hartley 2 in Cassiopeia
I managed to snag Comet Hartley 2 with the Nikkor 50mm f/1.4 AI lens. The comet is that green fuzzy just below Cassiopeia near the centre-right of the photo. It's nearing its closest approach to Earth on October 20 at 11 million miles away. There are reports it's beginning to sprout a tail.
