Özet

The field rotation effect can be described as observing the gyration of an object with the pupil of the Eastern Anatolian Observatory (DAG) telescope around the optical axis under the influence of the latitude of the observatory while the telescope is following that astronomical object. This is possible as a result of the alt-azimuthal mount of the telescope. (the orientation of the astronomical observed object, the parallactic angle, is defined as "q")
