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.

Low power eyepieces offer a wide field of view, bright, high-contrast images, and eye relief during long observing sessions. To 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 enlarge the image as much as practical for prevailing seeing conditions. NOTE: Seeing conditions vary widely from night-to-night and site-to-site. Turbulence

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
