Observer 60 EQ Parts Diagram 2 Congratulations on your purchase of a quality Orion telescope. Your new Observer 60 EQ Refractor is designed for high-resolution viewing of astronomical objects. [. . . ] In very cold climates (below freezing), it is essential to store the telescope as cold as possible. If it has to adjust to more than a 40° temperature change, allow at least one hour. Aiming the Telescope To view an object in the main telescope, first loosen both the R. A. Aim the telescope at the object you wish to observe by "eyeballing" along the length of the telescope tube (or use the setting circles to "dial in" the object's coordinates). Then look through the (aligned) finder scope and move the telescope tube until the object is centered on the crosshairs. Then center the object on the finder's crosshairs using the R. A. The object should now be visible in the main telescope with a low-power (long focal length) eyepiece. Focusing the Telescope Practice focusing the telescope in the daytime before using it for the first time at night. Start by positioning the focuser near the center of its adjustment range. Insert an eyepiece into the focuser and secure with the thumbscrew. Point the telescope at a distant subject and get it in the field of view. Now, slowly rotate one of the focusing knobs until the object comes into sharp focus. Go a little bit beyond sharp focus until the image just starts to blur again, then reverse the rotation of the knob, just to make sure you hit the exact focus point. The telescope can only focus on objects at least 50 to 100 feet away. It will not focus without the star diagonal in place. R. A. ­5° 27' That's 5 hours and 35. 4 minutes in right ascension, and ­5 degrees (5 degrees south of the celestial equator) and 27 minutes in declination. Before you can use the setting circles to locate objects, they must first be calibrated. The declination setting circle was calibrated at the factory, and should read 90° when the telescope optical tube is pointing exactly along the polar axis. If it does not read 90°, it may have to be reset. Calibrating the Right Ascension Setting Circle 1. Identify a bright star near the celestial equator and look up its coordinates in a star atlas. lock knobs on the equatorial mount (not the azimuth lock knob or latitude adjustment knob), so the telescope optical tube can move freely. [. . . ] Small components like eyepieces and other accessories should be kept in a protective box or storage case. Keep the objective lens cap on the front of the telescope when it is not in use. 8 Your Observer 60 EQ requires very little mechanical maintenance. The optical tube is aluminum and has a smooth painted finish that is fairly scratch-resistant. If a scratch does appear on the tube, it will not harm the telescope. [. . . ]
