O. 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. The Observer 60mm includes everything you need to go from box to backyard in less than half an hour. These instructions will help you set up, use and care for your new telescope. Table of Contents 1. [. . . ] It lies within 1° of the north celestial pole (NCP), which is an extension of the Earth's rotational axis out into space. To find Polaris in the sky, look north and locate the pattern of the Big Dipper (Figure 9). The two stars at the end of the "bowl" of the Big Dipper point right to Polaris. Observers in the Southern Hemisphere aren't so fortunate to have a bright star so near the south celestial pole (SCP). lock knobs (22, 24) 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. 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. 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°. 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. 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. Objects will then remain stationary in the field of view without any manual adjustment of the R. A. [. . . ] Wipe the lens gently in a circular motion, then remove any excess fluid with a fresh lens tissue. 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. [. . . ]
