10 Low power eyepieces offer a wide field of view , bright, high-contrast images, and eye relief during long observing sessions. T o find an object with a telescope, always start with a low power eyepiece ( e.g., 25mm or 26mm eyepiece). When the object is locat- ed and centered in the eyepiece, you may wish to switch to a higher power eyepiece to e[...]

21 • If inside a warm house or building, move outside. Interior air conditions may distort terrestrial or celestial images, making it difficult, if not impossible, to obtain a sharp focus. For optimal viewing, use the telescope outside in the open air instead of observing through an open or closed window or screen. • If viewing a land object on[...]

22 Celestial Coordinates A celestial coordinate system was created that maps an imaginary sphere surrounding the Earth upon which all stars appear to be placed. This mapping system is similar to the sys- tem of latitude and longitude on Earth surface maps. In mapping the surface of the Earth, lines of longitude are drawn between the North and South[...]
