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. Children should always have adult supervision while observing. INTRODUCTION Your telescope is an excellent beginner's instrument, and is designed to observe objects in the sky and also on land. [. . . ] The first thing you will notice is that not all stars are the same colors. The color of stars sometimes can tell you about the age of a star and the temperature that they burn at. Very often, you can find double (or binary) stars, stars that are very close together. A galaxy is a large grouping of stars, containing millions or even billions of stars. Some galaxies form a spiral (like our galaxy, the Milky Way) and other galaxies look more like a large football and are called elliptical galaxies. There are many galaxies that are irregularly shaped and are thought to have been pulled apart because they passed too close to--or even through--a larger galaxy. You may be able to see the Andromeda galaxy and several others in your telescope. Only very large telescope will reveal spiral or elliptical details. Looking at or near the Sun will cause irreversible damage to your eye. Do not look through the telescope as it is moving. You will also be able to see some nebulas with your scope. The two easiest to see in the Northern Hemisphere are the Orion nebula during the winter and the Triffid nebula during the summer. When you become an advanced observer you can look for other types of objects such as asteroids, planetary nebula and globular clusters. And if you're lucky, every so often a bright comet appears in the sky, presenting an unforgettable sight. The more you learn about objects in the sky, the more you will learn to appreciate the sights you see in your telescope. The best exercise for drawing is to observe the moons of Jupiter every night or so. Try to make Jupiter and the moons approximately the same size as they look in your eyepiece. As you get better at drawing, try more challenging sights, like a crater system on the moon or even a nebula. Go your library or check out the internet for more information about astronomy. Learn about the basics: light years, orbits, star colors, how stars and planets are formed, red shift, the big bang, what are the different kinds of nebula, what are comets, asteroids and meteors and what is a black hole. The more you learn about astronomy, the more fun, and the more rewarding your telescope will become. SOME OBSERVING TIPS Eyepieces: Always begin your observations using the 25mm low-power eyepiece. The 25mm eyepiece delivers a bright, wide field of view and is the best to use for most viewing conditions. Use the high-power 9mm eyepiece to view details when observing the Moon and planets. [. . . ] Check the amount of tension by moving the bracket up and down before reattaching the optical tube. OPTIONAL ACCESSORIES #928 45° Erecting Prism (1. 25 O. D. ): Correctly orients the telescopic image during terrestrial observing and yields an image position at a 45° angle to the main telescope tube, resulting in a more comfortable observing position in 13 Fig. (View of the underside of the base. ) · When absolutely necessary, dust on the front lens should be removed with very gentle strokes of a camel hair brush or blown off with an ear syringe (available at most pharmacies). · Fingerprints and organic materials on the front lens may be removed with a solution of 3 parts distilled water to 1 part isopropyl alcohol.
