This June 5th, I managed to show the Venus transit to our eager cubs. This safe projection from the telescope shows Venus and even some sunspots (very small). Note the orientation at right angle, facilitating the observation.
Lugging a scope in a park on Venus transit evening make you very popular among passer-by!
(Closer view; those pics were taken by a friend)
But the real magic moments were when birds (or planes!) crossed the enlarged sun projection.
