Introduction,g computer network now links astronomers, both professional and amateur, all over the world and connects them to the data and information they need. Email provides the former and the World Wide Web (WWW) the latter. I can recall the voyager missions and all those fabulous images. If only we could ha

All these programs will chart the sky for any date and place on Earth, some even as seen from other planets, although just how useful that would be i

Due to a technique called streaming you can have images, even sound and movies (with an a

Gone are the days when dark room wizardry was a prerequisite for successful imaging. We have already seen in Chapter 6 that real scientific work, such as astrometry and photome

The arrival onto the market of computer controlled commercial telescopes, appealing to today’s generation of IT literate amateur astronomers, has probably contributed to the myth that the amateur telescope maker can no longer compete. Nothing could be further from the truth.
