South Africa has had a long tradition in astronomical parallax measurements (Glass, 2008), so when the Astronomical Society of Southern Africa was approached by D. Cenadelli, University of Milan, to do a parallax collaboration, it was natural for an ASSA member, L. Ferreira, (Garden Route Centre, ASSA) to respond positively. The reason for this collaboration is, that for astronomical parallax measurements a large baseline is needed, usually the diameter of the Earth's orbit around the Sun. But for planetary parallax measurements an Earth-bound baseline was sufficient. For the Moon even less will do.
