If you mount your camera on a tripod and set your shutterspeed to more than 30 sec (bulb) and point your lens up to the sky you get this effect. It seem like the stars are moving.. surprise.. it is not. It is of course the rotation of our planet. I used shutterspeed 2837 sec on the first one and 1538 on the last one. That equals 47 minutes and 25 minutes. Be sure to have enough battery power :-)
Yesterday I went out around midnight, drove away from the city lights. I mounted my camera on my tripod and started an exposure for 25 minutes. I was out to capture some shooting stars, but the only extra in this pictures are the lights from a passing aircraft ( those two white spots up to the left might be due to low quality in my cheep lense.. I even see a part of a face in the sky, do you?). This is my first time trying this but not the last. Due to earth rotation this effect will occur when using long exposure time. Up in the right corner you see the Northern Star. I wish you all a beautiful SWF and a great weekend.
