"That's interesting. I would like to know the circumstances, and with what
instrument, Frank made that observation, when Venus was only 8 degrees North
of the Sun (ecliptically speaking)."
A fairly ordinary six-inch reflecting telescope with magnification around
75x on an equatorial mount with basic RA/Dec setting circles. The trick is to
look for Venus, in daylight around high noon. You aim the telescope at the
Sun, projecting the Sun's image, not looking directly. Then adjust for the
setting circles to match the Sun's position, and offset from there to Venus. As
long as the sky is very clear, Venus is visible immediately.
