Refracting telescope focus, results in a non-inverted and upright image. Galileo’s best telescope magnified objects about 30 times. Because of flaws in its design, such as the shape of the lens and the narrow field of view, the images were blurry and distorted. Despite these flaws, the telescope was still good enough for Galileo to explore the sky. The Galilean telescope could view the phases of Venus, and was able to see craters on the Moon and four moons orbiting Jupiter. Parallel rays of light from a distant object (y) would be brought to a focus in the focal plane of the
First on the Moon that in this case, Soviet cosmonauts were first. The movie follows the selection and training of a small group of cosmonauts. The one who shines above the others (similar to the clear front-runners in the early historical Soviet space program) is Captain Ivan Sergeyevich Kharlamov (possibly a reference to the real-life cosmonaut Valentin Varlamov). He is helped into a space suit and loaded into the capsule, and the rocket lifts off for the Moon—but contact with it is soon lost.
