[. . . ] Instruction Manual 8", 10", 12" LightBridgeTM Truss Tube Dobsonian Telescopes MEADE. COM CONTENTS WARNING! Never use a Meade Telescope to look at the Sun!Looking at or near the Sun will cause instant and irreversible damage to your eye. Eye damage is often painless, so there is no warning to the observer that damage has occurred until it is too late. Do not point the telescope or its finder at or near the Sun. [. . . ] It is average as far as stars go and is a middle aged star. Beyond the planets are clouds of comets, icy planetoids and other debris left over from the birth of our sun (the Oort cloud). Recently astronomers have found large objects in this area and they may increase the number of planets in our solar system. The four planets closest to the Sun are rocky and are called the inner planets. Mercury, Venus, Earth and Mars comprise the inner planets. Venus and Mars can be easily seen in your telescope. Venus is seen before dawn or after sunset, because it is close to the Sun. You can observe Venus going through crescent phases. But you cannot see any surface detail on Venus because it has a very thick atmosphere of gas. When Mars is close to the Earth, you can see some details on Mars, and sometimes even Mars' polar caps. But quite often, Mars is further away and just appears as a red dot with some dark lines crisscrossing it. Jupiter, Saturn, Uranus, Neptune and Pluto comprise the outer planets. These planets, except for Pluto, are made mostly of gases and are sometimes called gas giants. If they had grown much bigger, they may have become stars. Jupiter is quite interesting to observe. You can see bands across the face of Jupiter. The more time you spend observing these bands, the more details you will be able to see. One of the most fascinating sights of Jupiter are its moons. The four largest moons are called the Galilean moons, after the astronomer Galileo, who observed them for the first time. If you've never watched the Galilean moons in your telescope before, you're missing a real treat!Each night, the moons appear in different positions around the Jovian sky. This is sometimes called the Galilean dance. [. . . ] 12: Series 5000 5 Element Plossl Eyepieces. Series 4000TM Nebular Filters: A modern boon to the city-dwelling deep-space observer, the interference nebular filter effectively cancels out the effects of most urban light pollution, while leaving the light of deep-space nebular emissions virtually unattenuated. Meade Series 4000 Nebular Filters utilize the very latest in coating technology. Meade Laser Collimator: The Meade Laser Collimator is an easy to use collimation device. Poor collimation can cause planetary detail to be fuzzy and star images to appear elongated or irregular. [. . . ]
