O. Box 1815, Santa Cruz, CA 95061 IN 209 Rev. A 1/03 2 ® Welcome to the exciting world of amateur astronomy. Your new Observer 60mm 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. [. . . ] 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 (8) 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. control cable in a desired direction, you have reached the end of travel, and the slow-motion mechanism must be reset. This is done by first rotating the control cable several turns in the opposite direction from which it was originally being turned. Then, manually slew the telescope closer to the object you wish to observe (remember to first loosen the Dec. slow-motion control cable again to fine adjust the telescope's position. Tracking Celestial Objects When you observe a celestial object through the telescope, you'll see it drift slowly across the field of view. To keep it in the field, if your equatorial mount is polar aligned, just turn the R. A. slow-motion control cable (7) clockwise or counter-clockwise to keep it in the field of view (which way you turn depends on what side you have attached the control cable. slow-motion control cable is not needed for tracking. Objects will appear to move faster at higher magnifications, because the field of view is narrower. Optional Electronic Drives for Automatic Tracking An optional DC electronic drive can be mounted on the R. A. axis of the equatorial mount to provide hands-free tracking. Objects will then remain stationary in the field of view without any manual adjustment of the R. A. Understanding the Setting Circles The setting circles on an equatorial mount enable you to locate celestial objects by their "celestial coordinates". Every object resides in a specific location on the "celestial sphere". [. . . ] For the larger surface of the objective lens, clean only a small area at a time, using a fresh lens tissue on each area. Deep-Sky Objects Under dark skies, you can observe a wealth of fascinating deep-sky objects, including gaseous nebulas, open and globular star clusters, and a variety of different types of galaxies. Most deep-sky objects are very faint, so it is important that you find an observing site well away from light pollution. Take plenty of time to let your eyes adjust to the darkness. [. . . ]
