Another one from Kelling Heath - slowly getting through them.  A fixed lens looking at polaris (well it was at the start !).

90 x 120s ISO 1600 with a Canon 450d DSLR and 200mm lens @F/2.8
Images were binned 2x2 before an 'average' combine and slight process in PS

Images taken between 23:28PM on 24th and 02:33 on 25th April 2009.

Excellent Robert - I love that - Always fancied doing one of these myself but never got around to it...  What are the white points.... hot pixels??? Can you remove them..
