[. . . ] ASSEMBLING THE TELESCOPE: Numbers in parentheses refer to Fig. To assemble the telescope, first unfold the tripod legs (14). Place the hole on the bottom of the tripod attachment platform (15) over the bolt on the tripod attachment base (16) and tighten the holder attachment knob (17) to secure the optical tube to the tripod. Slide an eyepiece (1) into the erecting roof prism (3) and tighten the eyepiece thumbscrew (2) to a firm feel. [. . . ] The low power MA17. 5mm eyepiece presents a bright, wide field of view, ideal for terrestrial and general astronomical observing. For lunar and planetary viewing, switch to a higher power eyepiece such as the standard equipment MA9mm. Also consider using the provided 2X Barlow lens. If the image starts to become fuzzy as magnification is increased--back down to a lower power. See "Power" for more information about the Barlow lens. If you are observing an astronomical object, you will immediately notice that the object moves in a rather slow but continuous motion across the telescopic field of view. This motion is caused by the rotation of the Earth which results in the motion of the object in the telescope's field of view. To keep astronomical objects centered, simply move the telescope using the altitude (19) or horizontal (12) control knobs. In the higher power MA9mm eyepiece, astronomical objects will seem to move through the field more rapidly. Place the object on the edge of the field of view and watch as it drifts to the opposite side, then reposition the telescope so the object can drift through the field again. Avoid touching the eyepiece while observing. Vibrations resulting from such contact will cause the image to move. Viewing from the upper floors of a building may also introduce image movement. Allow a few minutes for your eyes to become "dark adapted" before you begin any serious observations. Some atmospheric conditions can distort an observed image. Planets, in particular, viewed while low on the horizon, lack sharpness. When observed higher in the sky, a planet will often appear to be more steady and have greater contrast. Turbulent air in the upper atmosphere can cause the images to "shimmer" in the eyepiece. Use the MA17. 5mm eyepiece until the image steadies. Keep in mind that a bright, clearly resolved, but smaller image will show far more interesting detail than a larger, dimmer, fuzzy image. A number of fascinating objects are visible through your Meade 70mm compact refractor: · · Jupiter: Jupiter has cloud belts across its surface. It's four major moons change position around the planet each night.
