As you view, epoch receives smarter and personalizes the knowledge for your interests and Choices. It is really like your television, only smarter.
If the time difference is smaller, then rather simple and smaller corrections for your precession may well suffice. If enough time variance will get substantial, then fuller plus more correct corrections has to be utilized. For this reason, a star place go through from the star atlas or catalog depending on a sufficiently previous equinox and equator can't be employed without the need of corrections if reasonable accuracy is necessary.
