My second attempt at star trails and this one's fairly noisy considering ISO 160 for 100 minutes...
My first go at long exposure star shots... www.twanight.org/newTWAN/news/6047-21.jpg found it's way to the short list on the TWAN dark sky awareness projects competition even though it was flawed.

These are fun but you tie up your gear for hours with no guarantee of good results so i lean towards the 30 sec. exposures in hope of catching a falling star.
