Star Trails Around Pole

20:10 24/8/2009 UTC

I've always wanted to take these star trail images, but for some reason I haven't done so during these years. This time I pondered around while my CCD setup was doing Heart Nebula and suddenly remembered star trails. I went inside, grabbed my trusty EOS 1000D, put it into tripod and set the timer remote to do 2 minute exposures. Easy and fun. Quite the opposite of narrowband work... (Don't get me wrong, NB is fun, but far from easy)
