Bushnell Video Scope Review

Observatory telescopes today are virtual behemoths compared to Galileo´s 1 3/4-inch-diameter (4.4 cm) models. His primitive devices were refracting telescopes. A large convex lens on one end formed the image and a small concave lens at the other end, later modified to be also convex, magnified the image. Remarkably, his instrument could magnify objects up to 33 times, allowing him to view such distant wonders as Venus´ moon-shaped phases and Jupiter´s four moons.

Today´s reflecting telescopes use immense, bowl-shaped mirrors (up to 236 inches [600 cm] across!) to collect light from faraway heavenly bodies. They are thus able to detect objects ten million times fainter than those that can be seen with the naked eye. Why, it is claimed that one telescope in Australia could detect a candle flame a thousand miles (1,600 km) away! Interestingly, though, astronomers today still run into the same problem Galileo faced. He noticed that the stars increased in number when magnified but not in size. Galileo calculated that the stars must be far away for them to be mere points of light when magnified.

The Role of Telescopes

The electron microscope was invented in 1931. By aiming a stream of electrons at an object, a visual image can be produced in which objects are magnified about a million times. It has one serious drawback: It cannot be used to study living specimens. A new device, however, which combines the optical microscope with television cameras and computer memory, now makes it possible for scientists actually to observe the biological activity of living cells! Telescopes and microscopes are thus potent tools. Mankind has been given an incredible insight into the world and universe in which he lives.

Yes, telescopes are making a positive impact on human knowledge. This tends to considerably increase the need for astronomers to find the right kind of telescope that they need due to all the many offers on the market. Bushnell telescope is only one among the many choices of the different kinds of telescopes in the market today.
