This 2000 Edition of Sir Patrick Moores classic book has been completely revised in the light of changes in technology. Not only do these changes include commercially available astronomical telescopes & software but also what we know & understand about the universe. There are many new photographs & illustrations. Packs a great deal of valuable information into appendices which make up almost half the book. These are hugely comprehensive & provide hints & tips as well as data (year 2000 onwards) for pretty well every aspect of amateur astronomy. This is probably the only book in which all this information is collected in one place.
