I have rectified the horoscope of Albrecht von Wallenberg.
Rectified time: 16h14m31s.
Gmt: 15h09m59s.
It was not easy to rectify but I am sure this horoscope is right!
Kepler had a time 16h01,5m00s.
This horoscope and the by me rectified horoscopes of Kepler, Copernicus, Galileo, Huygens and Brahe can be looked at on my website: www.andriescats,nl.
