Telescopes

You need to rotate the lenses round to get the best magnification then use the wheels on the side to bring it into focus. If this does not meet your requirement's then you need a better microscope.

Of conventional Telescopes the 200 Inch reflector at Mount Palomar also c alled the Hale telescope(from its designer) is probaly the top tube. for produc tion models there was an all-aluminum 72 Inch reflector in an altazimuth mount which was made by the then Kaiser aluminum corporation and was exhibited in the science section of Disneyland for many years, perhap still around. it resembed a mamoth theodolite.

East to west.

First answer by N4CUZ1.

To clarify, the sidereal day is the time it takes the earth to complete one rotation. i.e. One Day. So, depending on your telescopes mounting, equatorial primarily, the drive should rotate in the opposite direction of the earth's rotation to maintain an object in your view finder. Hence, west to east.

Cheers.

Just like any antenna used to collect electromagnetic energy at any other frequency,

the 'gain' is proportional to the antenna's area. Since the area varies as the square of

the collector's diameter, doubling the diameter increases the gain by a factor of 22 = 4.

The corresponding increase in gain is 6 dB.

Benjamin Banneker used a reflecting telescope that he built himself in the 18th century. This telescope was made entirely from wood and had a unique design with a 6-foot focal length. Banneker used his telescope to observe the stars and make detailed calculations for his almanacs.

Scientists send a variety of instruments and equipment to space to research space, such as telescopes, satellites, rovers, and even human astronauts. These tools help gather data on planets, stars, galaxies, and other celestial bodies, as well as study the effects of microgravity and space travel on living organisms.

The Hubble Space Telescope is repaired by sending Space Shuttle missions to it. Astronauts conduct repairs, upgrades, and maintenance tasks during these missions. They replace faulty components, install new instruments, and perform tests to ensure the telescope's functionality.

The Keck telescopes are optical, so no. The only possible exception being the super-luminous flash of Hawking radiation that theoretically occurs in certain-sized black holes, although orbital telescopes have a much better chance of detecting this light. Most of the electromagnetic radiation emitted from black holes has energies in the range of x-rays, an energy range that the Keck telescopes aren't designed for.

However, the most likely way that a black hole will be experimentally proven to exist is through the indirect method of measuring stellar orbits. Believe it or not, simple calculations from the ultra-precise, Keplerian orbital measurements of distant stars can be made to show the necessary size and mass of whatever object it is those stars are orbiting. If that size and mass fit the necessary conditions required of black holes, then there's your proof. The Keck telescopes are VERY well-equipped to make those kinds of measurements.

If an object is too far to be seen in a telescope, adjusting the focus of the object lens will not bring it into view. In such cases, the telescope may need to be repositioned or pointed towards a different direction in the sky to locate the object within the field of view. Additionally, using larger telescopes with a wider field of view may also help in locating distant objects.

HST gets its power from 2 large solar panels, located on either side of the spacecraft's main body. They are programmed to move to the optimal angle for sunlight absorption as it orbits the Earth, regardless of the angle of the spacecraft itself.

The original arrays were replaced on HST Servicing Mission 1 in December 1993, due to extensive warping caused by the constant change in thermal temperatures as it passed through the day/night terminator orbiting the Earth every 90 minutes. The arrays installed during SM1 were replaced on Servicing Mission 3B in March 2002. The new ones are much heavier, more efficient, and designed to better withstand the extreme thermal changes, which can go from 140°C to - 140°C.

Scientists should continue to improve telescopes to enhance our understanding of the universe by capturing clearer images of distant celestial objects, allowing us to uncover new discoveries and insights into the nature of the cosmos. Upgrading telescopes can also help us observe more precise details, measure distances more accurately, and study various phenomena in greater depth, ultimately advancing our knowledge of the universe.

Not necessarily. Refracting telescopes can be large, but reflecting telescopes can also be quite large and often have larger apertures due to their design. The size of a telescope depends on its purpose and design specifications rather than whether it is refracting or reflecting.

The objective lens or mirror in a telescope magnifies the image by gathering and focusing light from distant objects.

The most common type of reflecting telescope produces an inverted image. However, it's possible for a reflecting telescope to produce an upright image, depending on exactly how the optics are arranged.

The telescope was invented in 1608 by Hans Lippershey, a Dutch eyeglass maker. This early version of the telescope consisted of a convex objective lens and a concave eyepiece lens. The invention of the telescope revolutionized astronomy by allowing astronomers to observe objects in the sky with greater detail and precision.

The Hubble Space Telescope is a powerful telescope that orbits Earth and captures images of distant galaxies, stars, and other celestial objects. It has provided significant contributions to our understanding of the universe and has been in operation since 1990.

The James Webb Space Telescope is an infrared telescope, designed to observe objects in the infrared spectrum. It covers a range of wavelengths from about 0.6 to 28 micrometers.

An observatory is a room containing telescopes for studying planets. These facilities are typically equipped with advanced instruments and technology to observe celestial bodies in detail. Scientists use observatories to conduct research on planets, stars, and other astronomical phenomena.

Ultraviolet telescopes are used to observe celestial objects emitting ultraviolet radiation, which is not visible to the human eye. They provide valuable information about the composition, temperature, and dynamics of stars, galaxies, and other astronomical phenomena that emit UV light. This can help astronomers study the formation of stars, the evolution of galaxies, and the presence of elements in the universe.

Some nebulae that can be seen without a telescope include the Orion Nebula (M42), the Lagoon Nebula (M8), and the Andromeda Galaxy (M31). These objects are bright enough to be visible to the naked eye under dark skies.

The Chandra Telescope uses x-rays to examine outer space.

The simplest optical telescope typically consists of two main components: a concave objective lens or mirror that collects light and forms an image, and a smaller eyepiece lens that magnifies and brings the image into focus for the observer. These components come together to allow for viewing distant objects in greater detail by gathering and focusing light.

Non-reflecting film is a type of film that is designed to reduce glare and reflection caused by light. It is commonly used on displays, windows, and lenses to improve visibility and clarity by minimizing light distortion. This type of film is often preferred in environments where maintaining a clear view is important.

People commonly look through telescopes to see into space. Telescopes are used by NASA to see stars and planets very far away, and less sophisticated models are used to see planets in our solar system, or even the moon.
