Crickey!, I must mention that that people should NEVER look at the Sun through any type of optical instrument unless they know what special precautions to take!! Instant, permanent blindness will result!!! Do not ever do this without learning about it properly first. Learn from astronomers. I know this will be obvious to most people here, but it's not something to be undertaken lightly. Despite my frivoloty above, I was very cautious, especially as I was sharing the experience with novices. Phew.
