6 T elescope and T ripod Features b Dust Cap (not shown) : Pull to remove from the de w shield ( 17, Fig. 1 ). NO TE: The dust cap should be replaced after each obser ving session and the power turned off (NGC models only) to the telescope.
7 1) Focus Knobs : Use to mov e the telescope’ s f ocuser assembly to obtain precise image f ocus. Rotate the focus knobs cloc kwise to focus on distant objects , and counterclockwise to f ocus on nearby objects . 1! T ripod Leg Nuts and Bolts (3): Attach the tripod legs ( 15, Fig.

10 located and centered in the ey epiece, y ou may wish to s witch to a higher pow er eye- piece to enlarge the image as much as practical f or pre vailing seeing conditions . NO TE: Seeing conditions vary widely from night-to-night and site-to-site. T urbulence in the air , ev en on an apparently clear night, can distor t images.
11 After displa ying "Then Press Enter ," the control panel displays tw o numbers, one on each line. F or example: "+35 -115." These two numbers are called " displace- ment numbers " and will assist y ou in locating a celestial object.
12 Ne xt, move the tube upw ard or downw ard until the second displacement number also reaches zero . As you near zero , use the ver tical slow motion control ( F , Fig. 3 ) to mov e the optical tube. If you perf or med the alignment procedure correctly , Saturn will appear in your ey epiece.

How to Mo ve thr ough Menu Options (NGC Models Only): It is helpful to understand that menu selections are set in a loop . This means that press- ing the DO WN button scrolls down through all the a vailab le options within a given cate- gor y , then returns to the first option.
15 Object Menu Almost all obser ving is perf ormed using the Object menu categor y . ( NO TE: Exceptions include Guided T our and Landmark Sur ve y . ) See GO TO SA TURN , page 13, for an e xample of obser ving using the Object menu. Also see USING THE GUIDED T OUR , page 13.

Moonrise and Moonset calculates the time that the Moon rises or sets on the current date and location. Find rise and set times for other dates b y entering a new date into the "Setup: Date" menu.
• Magnification: Scroll through a list of a vailab le ey epieces. When an ey epiece is selected, the magnification is calculated. • Suggest: Suggests the best ey epiece for vie wing, based on the telescope and the object being view ed.
OPTIONAL A CCESSORIES 18 A wide assor tment of prof essional Meade accessories is availab le for the NG-Series and NGC-series telescopes. Consult the Meade General Catalog for complete details of these and other accessories. Eyepieces (1.25" barrel diameter): F or higher or lower magnifications with the tele- scopes that accommodate 1.
19 General Maintenance Y our telescope is a precision optical instrument designed to yield a lifetime of re ward- ing applications. Given the care and respect due any precision instrument, your tele- scope will rarely require f actor y servicing or maintenance.
20 • If inside a warm house or building, mov e outside. Interior air conditions may distort terrestrial or celestial images, making it difficult, if not impossible , to obtain a shar p f ocus. F or optimal viewing, use the telescope outside in the open air instead of obser ving through an open or closed window or screen.
21 Celestial Coordinates A celestial coordinate system was created that maps an imaginary sphere surrounding the Ear th upon which all stars appear to be placed. This mapping system is similar to the sys- tem of latitude and longitude on Ear th surf ace maps.
22 6. "Right Asc.: 00.00.0" displays . Use UP/DOWN and ENTER to enter the digits f or the Right Ascension coordinate of your object. 7. "Declination: +00°.00'" displa ys. Use UP/DOWN and ENTER to enter the digits f or the Declination coordinate of your object.
How to manuall y set the date to March 6, 2005 (NGC Models Only): 1. Press ON/OFF to tur n on the control panel. 2. Press the button prompted by the control panel to sho w that the Sun warning has been read and understood. 3. Keep pressing MODE until “Select Item: Object” displays.
24 Replace the red dot Viewfinder’ s batter y with a CR2032 lithium battery . The batter y is locat- ed on the bottom of the red dot viewfinder . Y ou may need to slide y our finger nail or a screw- driver b lade under neath the battery and then slide it out.
25 In the early 17th centur y , Italian scientist Galileo , using a cr ude telescope smaller than your NG or NGC , turned it to look towards the sky instead of distant trees and moun- tains. What he saw , and what he realized about what he saw , fore ver changed the w ay mankind thought of the universe .
