Stars tracker

thingiverse

To photograph the night sky, use long exposures for maximum light capture; however, due to Earth's rotation, stars move rapidly. This device cancels apparent star movement during long exposures. Turn the handle every minute with a 50mm lens, but every 15 seconds for optimal results. Print all five STL files and assemble the parts accordingly, then attach to a camera tripod. Align the celestial north pole using the alignment scope tube before starting your exposure. After each 15-second interval, turn the wheel 1/4 turn clockwise until the end of exposure. Begin with 2-minute exposures at over 800 ASA for best results.
