For a telescope to accurately track the sky motion of any celestial object like planets, stars, and deep-sky objects, precise polar alignment is needed. This is true for any equatorial telescope, both for manual and electronic types. Without proper polar alignment, objects will always drift out of view making it impossible to perform lengthy and detailed observations. In astrophotography, poor polar alignment would mean sad-looking star trails in captured images.
