5 of engagement on the shafts . The mirror cell is now ready to be installed into the tube. Assembling the SkyQuest XT12 mirror cell to the tube can be a bit tricky . This is because the large diameter and thin steel of the tube will cause the tube to become somewhat out of round once the rear end ring is removed.
6 tighten them until firm, but be careful not to strip the holes by over-tightening. If you use an electric screwdriver , do final tightening with a standard screwdriver to avoid stripping. 1. Screw the plastic feet into the underside of the ground baseplate (A) using the se lf-tapping wood s crews pr ovid- ed, with a Phillips screwdriver .
7 panel of the base you will notice two predrilled starter holes, about 6" apart. T ake the black wood screws and thread them into the starter holes with a Phillips screwdriver . Then you can “keyhole” the eyepiece rack onto the wood screws and con- tinue tightening the screws (Figure 1 1).
8 should seat onto the narrow end of the spacer . Repeat this procedure for the other altitude side bearing. 3. Attach a pull loop to the free end of each spring.
9 lev el, b ut it should be place d on som ewh at flat groun d or pav e- men t t o en sur e s moo th move men t o f t he tele sco pe. Remember , never point the telescope at or near the Sun with- out .
10 screws will be needed until the object comes into the finder scope’s field of view . The SkyQuest XT12’s finder scope uses a spring-loaded bracket that makes alignment of the finderscope very easy . As you turn either of the thumbscrews, the spring in the bracket’s tensioner moves in and out to keep the finder scope secure in the bracket.
11 expect the user to compensate for heavier accessories by adding weight to the opposite end of the telescope tube. Such counterweighting systems can be expensive and unwieldy . The CorrecT ension Friction Optimization system of the SkyQuest XT12 Dobsonian, however , solves the finicky bal- ance problem.
12 has a hole in the cente r and a silv er bot tom. This helps cente r your eye so that collimation is easy to perform. Figures 19b throug h 19e assume you ha ve the collim ation cap in place. In addition to the collimation cap, the primary mirror is marked with a circle at its exact center .
13 Now , try tightening or loosening one of the larger collima- tion thumbscrews with your fingers (Figure 23). Look into the focuser and see if the secondary mirror reflection has moved closer to the center of the primary .
14 3000 feet. Alti tude helps because it decreases the amount of distor tion c ausing atmosp here yo u are lookin g throu gh. A good way to judge if the seeing is good or not is to look at bright stars about 40° above the horizon.
15 bright objects, like planets and double stars. The Moon also takes higher magnifications well. Deep-sky objects, however , typically look better at medium or low magnifications. This is because many of them are quite faint, yet have some extent (apparent width).
16 of the stars and locate many pretty double and multiple stars. The famous “Double-Double” in the constellation L yra and the gorgeous two-color double star Albireo in Cygnus are favor- ites. Defocusing a star slightly can help bring out its color .
17 possible to take pictures of bright objects. Certain photo- graphic aids, such as the Orion SteadyPix, can help in taking photos by the afocal method. 6. Car e and Maintenance If you give your telescope reasonable care, it will last a life- time. Store it in a clean, dry , dust-free place, safe from rapid changes in temperature and humidity .
