O. Box 1815, Santa Cruz, CA 95061 IN 211 Rev. A 10/02 2 ® Welcome to the exciting world of amateur astronomy. Your new Observer 70 EQ Refractor is a quality optical instrument that will deliver countless hours of exciting stargazing, from magnified views of the Moon, star clusters, and nebulas to glimpses of Jupiter's moons and Saturn's rings. [. . . ] Then retighten the latitude lock T-bolt. The latitude setting should not have to be adjusted again unless you move to a different viewing location some distance away. lock knob (25) and rotate the telescope optical tube (1) until it is parallel with the R. A. setting circle (22) should read 90°. Loosen the azimuth lock knob (31) at the base of the equatorial mount (5) and rotate the mount so the telescope tube (and R. A. If you cannot see Polaris directly from your observing site, consult a compass and rotate the mount so the telescope points North. The equatorial mount is now polar aligned. From this point on in your observing session, you should not make any further adjustments in the azimuth or the latitude of the mount, nor should you move the tripod. The telescope should be moved only about its R. A. slow-motion control cables (8, 9) allow fine adjustment of the telescope's position to center objects within the field of view. Before you can use the cables, you must manually "slew" the mount to point the telescope in the vicinity of the desired target. lock knobs (23, 25) and moving the telescope about the mount's R. A. Once the telescope is pointed somewhere close to the object to be viewed, retighten the mount's R. A. The object should now be visible somewhere in the EZ Finder II (4). If it isn't, use the slow-motion controls to scan the surrounding area of sky. When the object is visible in the EZ Finder II, use the slow-motion controls to center it. Now, look in the telescope's eyepiece. If the EZ Finder II is properly aligned, the object should be visible somewhere in the field of view. Once the object is visible in the eyepiece, use the slowmotion controls to center it in the field of view. slow-motion control cable (9) can move the telescope a maximum of 25°. slowmotion mechanism has a limited range of mechanical travel. slow-motion mechanism has no limit to its amount of travel. ) If you can no longer rotate the Dec. [. . . ] Then apply some cleaning fluid to a tissue, never directly on the optics. Wipe the lens gently in a circular motion, then remove any excess fluid with a fresh lens tissue. Oily fingerprints and smudges may be removed using this method. Use caution-- rubbing too hard may scratch the lens. [. . . ]
