Accurate polar alignment for a telescope to a few arcminutes

  • 11 years ago
A short video describing how to get accurate polar alignment of an EQ2 GEM or similar using a Samsung SDC435 video camera or webcam. Alignment to the celestial pole accurate to a few arc minutes is possible.

The only requirements are that the pole star, Polaris, is visible and that the RA axis can be moved through 180o in a few seconds.
