Kochab method
The Kochab method is a method presented by the German amateur astronomer Heinz Lotze, with which an equatorial (parallactic) telescope mount can be precisely aligned with the celestial pole , which is used especially in amateur astronomy . The process takes about one to two minutes and is sufficiently accurate to be able to use astrophotography in the amateur field .
The Kochab method is an empirically determined method for northing up , which makes use of the fact that the north celestial pole , the star Polaris and the star Kochab are on a line. An equatorial (parallactic) telescope mount and a polar finder telescope as well as a clear view of Polaris are required.
In contrast to the more precise Scheiner method , which follows an iterative approach, the Kochab method achieves an alignment of the axes that is sufficiently precise for most applications in a very short time, so that it is very popular in amateur circles.
In the English-speaking world, the method is known as "Clay's Kochab Clock".
