deep Comet Lulin image

Hi all
After the Newcastle Astronomical meeting the skies had cleared up to a lovely dark sky and a cool night.

14x3 minutes, ISO400. cannon 300mm f2.8 lens from Bert. LPS filter, modded 350D.
Scott

EDIT: Ive added an image without star size reduction, it seems to be a little cleaner as the reductions indroduces some noise, also a cropped image masked with a 4x30 sec image to show the central condensation
