Telescope and Tripod Features b Dust Cap (not shown): Pull to remove from the dew shield (17, Fig. 1). NOTE: The dust cap should be replaced after each observing session and the power turned off (NGC models only) to the telescope. Verify that any dew that might have collected during the observing session has evaporat- ed prior to replacing the dust cap. C Optical Tube: The main optical component that gathers the light from distant objects and brings this light to a focus for examination with the

Rotate the focus knobs clockwise to focus on distant objects, and counterclockwise to focus on nearby objects. 1! Tripod Leg Nuts and Bolts (3): Attach the tripod legs (15, Fig. 1) to the tripod head (16, Fig. 1) using these three nuts and bolts.

After displaying "Then Press Enter," the control panel displays two numbers, one on each line. For example: "+35 -115." These two numbers are called "displace- ment numbers" and will assist you in locating a celestial object. 4. Move the telescope: Move the telescope tube to the right or left and you will notice the first displacement number getting larger or smaller. Move the tube in the direction that makes the number smaller. Keep moving the tube until the num- ber nears zero. As you near zer

Next, move the tube upward or downward until the second displacement number also reaches zero. As you near zero, use the vertical slow motion control (F, Fig. 3) to move the optical tube. If you performed the alignment procedure correctly, IMPORTANT NOTE: Saturn will appear in your eyepiece. You may need to center the image. As you observe 7.

How to Move through Menu Options (NGC Models Only): It is helpful to understand that menu selections are set in a loop. This means that press- ing the DOWN button scrolls down through all the available options within a given cate- gory, then returns to the first option. Pressing the UP key scroll up through the options IMPORTANT in the opposite order. Note that this capability is a quick way to get to an option that is NOTE: No matter near the bottom of the list.

Object Menu Almost all observing is performed using the Object menu category. (NOTE: Exceptions include Guided Tour and Landmark Survey.) See GO TO SATURN, page 13, for an example of observing using the Object menu. Also see USING THE GUIDED TOUR, page 13. The Object Menu includes: Solar System is a list of the eight planets (Earth is not included) in order out from the Sun, followed by the Moon, asteroids, and comets.

ACCESSORIES OPTIONAL ACCESSORIES A wide assortment of professional Meade accessories is available 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): For higher or lower magnifications with the tele- scopes that accommodate 1.25" eyepieces, Meade 3-element Modified Achromatic eye- pieces, available in focal lengths of 9, 12, 25, and 40mm, provide a high level of image resolution and

MAINTENANCE AND SERVICING General Maintenance Your telescope is a precision optical instrument designed to yield a lifetime of reward- ing applications. Given the care and respect due any precision instrument, your tele- scope will rarely require factory servicing or maintenance. Maintenance guidelines include: 1. Avoid cleaning the telescope’s optics. A little dust on the front surface of the tele- scope’s lens causes virtually no degradation of image quality and should not be considered reason

• 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 a warm day, heat waves distort the image. See SIMPLE OBSERVATIONS, page 10. • For clear viewing of objects, turn the focus knob (10, Fig. 4) slowly since th
