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

Virtual Sky Watching, of computing, sky simulations have been probably the biggest selling of all astronomical software. No astronomer worth his salt would be without one. 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

Hotel bookings along the path of totality are virtually all gone but there will be another way to watch this (and subsequent ones for that matter). What I am talking about is web broadcasts. Due to a technique called streaming you can have images, even sound and movies (with an a

Astrometry and Photometry: Real Science,e probably been responsible for this. Firstly the European Space Authority’s Hipparcos Space Astrometry Mission, which produced a celestial treasure trove of astrometric and photometric data, the accuracy of which had never been seen before. The second was the advent of affordable CCD cameras for th

CCD Imaging and Image Processing,ight than conventional film, they deliver a digitised image which is easy to enhance and analyse using a personal computer. 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

Telescope Making,ted with your own hands. 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.

Satellite Tracking,end of the day on which new elements are published, thousands will have logged on and copied them into their satellite tracking program. I can remember as a boy seeing one of the early Sputniks going overhead — it was visible proof that the USSR had taken an early lead in the space race. From the ea
