In the early part of the eighteenth century, Francesco Bianchini of Verona turned his primitive telescope - a refractor of only a few centimetres aperture but with an enormous focal length of around 20 metres - on the planet Venus. He recorded some of the first telescopic observations of Venus, outstanding in terms of care and accuracy. Bianchini determined the parallax of the planet, estimated the period of rotation, and carefully mapped surface features (although we now know that only Venus' atmospheric clouds can be seen in visible light).
