First sentence: Prior to the ETX, most inexpensive consumer telescopes came in two varieties: the refractor telescope, which uses a glass lens at the top to focus the light, and the Newtonian reflector telescope, which uses a curved mirror (actually a spherical surface) at the bottom to reflect and focus the light.
Description: In 1996 Meade, the world's largest astronomical telescope manufacturer, introduced the ETX, a low-cost and genuinely portable instrument capable of results close to the theoretical limits of optical performance. Since then several different models have been introduced, most of them controlled by on-board computers that automatically point the telescope at objects selected from a database of 12,000. Unfortunately not all these objects are visible when looking through the ETX! (They are included because they can be imaged with special equipment.) Mike Weasner is a world expert on the ETX range, and describes the "best" 100 objects to start with, and offers hints and tips about using and looking after the telescope to get the best possible results.
