Observing Considerations · Try to pick an observing site away from street and house lights, and car headlights. Give your eyes about ten minutes to adjust to the darkness before observing. Give your eyes a rest from observing every ten or fifteen minutes to relieve eyestrain. Seasoned observers use red LED flashlights or tape red cellophane over their flashlights for setup and map reading so they don't have to continually readjust their eyes to the darkness. Be careful not to shine bright lights if there are other observers in the area. [. . . ] Deep-Sky Objects Star charts can be used to locate constellations, individual stars and deep-sky objects. 36: Saturn has the most extensive ring structure in our Solar System. Fig. 37: The Pleiades is one of the most beautiful open clusters. Stars are large gaseous objects that are self-illuminated by nuclear fusion in their core. Because of their vast distances from our solar system, all stars appear as pinpoints of light, irrespective of the size of the telescope used. [. . . ]
