Page 5: Tripod Assembly
Tripod assembly Slowly loosen the tripod locking knobs and gently pull out the lower section of each tripod leg. Tighten the screws to hold the legs in place. Spread the tripod legs apart to stand the tripod upright. Adjust the height of each tripod leg until the tripod head is properly leveled. Note that the tripod legs may not be the same length when the mount is leveled. - Page 6 For models with bracket ring clamps: Remove the ring clamps from the telescope tube by releasing their thumb nuts and opening their hinges. Fasten the bracket with ring clamps to the mount through one of three holes. To lock the bracket, rotate the black riffled wheel inside the mount base.
- Page 7 Models with fork mount Remove the locking screw from the slow-motion control rod. Insert the rod into the hole on the side of the fork mount. Place the telescope tube between fork arms so that holes on the tube match the arm holes. Fasten the telescope tube to the mount with thumbscrews.

Page 8: Finderscope Assembly
Finderscope assembly Optical finderscope Optical finderscopes are very useful accessories. When they are correctly aligned with the telescope, objects can be quickly located and brought to the center of the view. Alignment is best done outdoors in day light when it's easier to locate objects. If it is necessary to refocus your finderscope, sight on an object that is at least 500 yards away. - Page 9 Scope Azimuth adjustment knob Brightness control Altitude adjustment knob Battery compartment cover Like all finderscopes, the red dot finder must be properly aligned with the telescope before use. This is a simple process using the azimuth and altitude adjustment screws: Open the battery compartment by pulling down the cover and remove the plastic shipping cover over the battery.
- Page 10 Zenith Meridian Latitude (270°) (0°/360°) (90°) Nadir (180°) Rotation around the azimuth axis Nadir Reference materials usually list declination coordinates in degrees, hours and minutes above or below the horizon line. Azimuth coordinates may sometimes be listed with the compass points (N, SW, ENE, etc.), but it is more commonly listed in degrees around the 360-deg plane, where north is 0°, east is 90°, etc.

Focusing Slowly rotate the focus knobs under the focuser one way or the other until the image in the eyepiece is sharp. The image usually has to be finely refocused over time, due to small variations caused by temperature changes, flexures, etc. This often happens with short focal ratio telescopes, particularly when they haven't yet reached outside temperature. -
Page 12: Field Of View
Magnification = Focal length of the telescope / Focal length of the eyepiece e.g. 800mm / 10mm = 80x When you are observing astronomical objects, you are looking through a column of air that reaches to the edge of space and that column seldom stays still. Similarly, when viewing over land you are often looking through heat waves radiating from the ground, houses, buildings, etc. -
Page 13: Weather Conditions
Weather conditions Sky conditions are usually defined by two atmospheric characteristics, seeing, or the steadiness of the air, and transparency, light scattering due to the amount of water vapor and particles in the air. When you observe the Moon or planets, and they appear as though water is running over them, you probably have bad "seeing"... -
Page 14: Maintenance
Replace the dust cap over the front end of the telescope whenever it is not in use. This prevents dust from settling on the lens. Be careful when cleaning optics and try not to damage the coating. Use only special cleaning wipes. Specifications Levenhuk Skyline 80х400 AZ Optical design refractor Aperture... -
