Amateur astronomers of all levels will appreciate this guide to choosing and caring for astronomy equipment, which also serves as a reference to terms and concepts (e.g., how the Rayleigh criterion relates to optical quality and the differences between various telescope and eyepiece designs).

Appendices include telescope and eyepiece specs by price range and astronomical yellow pages"
