Actually, the results from Galileo's telescope were ambiguous and required expert observation, training and patience.
It may seem a little odd to talk about expert training for a brand new instrument type, such as the telescope. What I mean is you had to be an expert astronomer. A naked-eye astronomer, such as Tycho Brahe, who was the last and greatest of them. It is a shame he never got a chance to use a telescope. If he had, he would have known instantly what he was seeing despite the problems with the early instruments.
Along the same lines, in 1989 and 1990, experts in electrochemistry, tritium and other related subjects were confident that they knew what they were saying when they first observed cold fusion, even though it was the first time in history anyone ever saw it.
