Observing the Ascendant and MC with a planisphere.

If you have a planisphere, observing the ascendant and MC for a certain time and date is very easy. See the instruction below.

    The intersection at the left-hand side is the ascendant, the right-hand side is the descendant.
  3. Set a ruler vertically on the center of the planisphere (the green line on the diagram below).
  4. Find the intersections of the ecliptic and the ruler. The intersection in the oval window is MC, the other side ( covered side ) is IC.
