Richard,

Great images. It was a stunning sight last night for those of us lucky
enough to have clear skies. I have loads of images of the comet and the
really spectacular NLCs from this morning but I have rushed to process a
couple taken with different focal lengths, 80mm and 200mm. In both cases
the photocentre is not saturated so there should be a load of detail I
can pull out later.

Hoping for clear skies again tonight. This must be the best comet seen
from the UK since Hale-Bopp in 1997.

Nick.
