This telescope is a precision scientific instrument. With it you will enjoy numerous objects in the sky—planets, nebulae, star clusters, galaxies and other astronomical objects. But, before your journey begins take time to read this manual to familiarize yourself with the operation and parts of this telescope. WARNING—NEVER LOOK AT THE SUN WITH YOUR TELESCOPE OR ITS FINDERSCOPE. PERMANENT AND IRREVERSIBLE EYE DAMAGE MAY RESULT AS WELL AS DAMAGE TO YOUR TELESCOPE. HOWEVER, YOU MAY ENJOY LOOKING AT THE SUN IF YOU HAVE A SAFE METHOD OF DOING SO—A SOLAR FILTER. IF USING A SOLAR FILTER, MAKE SURE THE FINDERSCOPE IS COVERED. 2. TELESCOPE ASSEMBLY Please refer to figures 1 and 2 (and the identifying parts list) as you assemble the telescope. The telescope and all items are packed in one box. Included are: • Telescope Optical Tube • German Equatorial Mount • Adjustable Wood Tripod • Counterweight Shaft and Counterweight • Tripod Accessory Tray • Declination Cable • Right Ascension Cable • 25mm SMA Eyepiece - 1'/«" (16x) • Diagonal - I1/*” • Finderscope, 6x30 A. Locate the German equatorial mount and the tripod legs along with the tripod mounting hardware and the tripod accessory tray. 1. Lie the tripod head (#7) on its side. Attach the three tripod legs (#12) one by one to the tripod head with the bolts and wing nuts (#17). Do not overtighten the bolts but just make them lightly finger tight. Remember to have each tripod leg in the right orientation with the tripod tray bracket (#11) facing inward. 2. Next, put the bolts and wing nuts in the bottom of the tripod legs through the holes for the height adjustment you want. We suggest you keep it at the lowest height for assembly (you can raise it later if you wish) and for maximum rigidity. NOTE—this may have been assembled at the factory. 3. Now set the tripod with the equatorial mount attached in the standing position by spreading the legs apart far enough for the tripod accessory tray (#11) to fit. 4. You are now ready to install the tripod accessory tray (#11). The tripod tray bracket fits into slots in the bottom of the tray (use the holes on the ends of the brackets). Use the bolts and wing nuts to attach each bracket to the tray. 5. Tighten all bolts and wing nuts to ensure proper stability. B. Before proceeding further, locate knobs #19 and #16 and tighten them finger tight after orienting the mount as illustrated in figure 1. 1. Locate the decimation cable holder (where #21 fits on). Locate the declination cable (the shorter of the two cables) and attach the cable (#21) to the cable holder by tightening the thumb screw on the cable end. The thumb screw should be tightened down hard on the flat surface of the cable holder after backing off the cable about 1/4" from being fully engaged. This method helps ensure there is no slippage when using the cable. 2. You may reverse the position orientation of the Declination cable to suit your preference if desired. 3. Locate the right ascension cable holder (where #18 fits on). Locate the right ascension cable (#18) and attach it the same way as the declination cable was attached in the last section. 4. Slide the counterweight shaft (#9) through the counterweight (#8). Use the counterweight lock (#10) to lock the counterweight in place. By holding the counterweight in one hand, thread the counterweight shaft clockwise into the equatorial mount as shown in figure 1. C. You are now ready to put the telescope optical tube (#2) onto the equatorial mount (#6). The optical tube is held to the mount with two mounting rings. On the bottom of the mounting rings are square extrusions — one on each ring. This portion of the ring slides over the ends of the mounting platform to hold the telescope in place (see figure 2). 1. Loosen the knurled screws on the side of the mounting rings and remove the tube ring closest to the focuser end of the optical tube. 2. Slide the remaining tube ring towards the objective end of the telescope tube. 3. Place the telescope tube on the mounting platform and orient it so that the objective lens is opposite the slow motion control handles. 4. Slide the attached tube ring down until the square extrusion fits over the end of the mounting platform. 5. Insert one of the mount platform screws through the bottom of the square extrusion and thread it into the mount. 6. Open the second tube ring and place the square extrusion under the other end of the mounting platform. 7. Close the tube and slightly tighten the knurled screw to hold the tube ring in place. 8. Thread the second mounting screw through the square extrusion of the tube ring and into the mounting platform. Tighten both mounting screws. 9. Tighten the knurled screws that clamp the mounting rings in place . This will keep the telescope from sliding back and forth in the mounting rings. D. Put the diagonal (#23) into the focuser (#22) and tighten the thumb screw on the focuser to hold it in place. E. Put th...
