Telescopes

Unfortunately, no.

No, a telescope and a microscope are not the same. A telescope is used to view distant objects such as stars and planets, while a microscope is used to view tiny objects such as cells and bacteria. Telescope magnifies objects that are far away, while a microscope magnifies objects that are small and nearby.

The first person to look at the night sky with a telescope and record what he saw and try to make deductions from his observations was Galileo Galilei. Galileo had a difficult personality and he tried to assert that he was the only person allowed to make astronomical discoveries with a telescope, but, putting that aside, he was a serious scientist who made several important discoveries in physics.

Because X-rays can't penetrate Earth's atmosphere. In other words, the

air soaks them all up, and none reach the ground. So an X-ray telescope

located on the ground would never see any, and would be quite useless.

The two major telescopes are refractive and reflective. Refractive uses two lenses and a 45 degree mirror. Lense, mirror lens. Reflective uses an open tube.light come in and strikes a concave mirror. Reflects back to the opening where a flat 45 degree mirror reflects light into an eyepiece lense that is near the opening. Images in a reflective telescope are backward without the use of an erecting prism. Further research for you, Dobsonian, Cassegrain.

Eyepiece, Primary Mirror, Secondary Mirror, Prime Focus.

X-ray telescopes collect the X-rays that are emitted from the sun, stars, and super novas in space using a series of curved lenses and an electronic eye.

well i can tell you what it is but im not quit sure what you mean by an example.... it is a optical instrument for viewing objects that are above the level of direct sight; mostly used in submarines

Hubble is better than ground-based telescopes because it operates above Earth's atmosphere, which can distort and block visible light. This allows Hubble to capture clearer and sharper images of the cosmos. Additionally, its position in space provides a wider field of view and enables it to observe ultraviolet and infrared wavelengths that are not easily accessible from the ground.

No. The Hubble Space Telescope is an optical telescope of the reflective type. A 'non optical' telescope would be one that works on different portions of the electromagnetic spectrum below or above the optical wavelengths.

The Hubble Space Telescope was built by a team of thousands of engineers, scientists, and technicians from NASA and the European Space Agency (ESA). It was a collaborative effort that involved contributions from multiple individuals and organizations.

Most optical magnifying units use compound lenses. Lenses that are made to focus light onto a spot or spread it out. A combination of them makes the best optics. Lenses are ground as convex and concave.

Several things limit which celestial objects can be seen with a telescope on Earth.

- The apparent magnitude of the object.

- The telescope you are using, tracking system and camera capability.

- Weather conditions, atmospheric and light pollution affecting airglow.

- The elevation of the object: lower in the sky means a thicker slice of atmosphere to interfere, more limitation.

- Your elevation relative to sea level: lower elevation means a thicker slice of atmosphere to interfere, more limitation.

- Red Shift - the object you are observing is moving away so fast that the color of the light reaching us has dropped into the infrared range, invisible to the human eye.

Generally, the faintest objects observable in visible light with 8m ground-based telescope is about 27.

light hits tiny microscopic beads or sattelite dishes or cube corner prisms, then light is reflected back to original light source to create glowing effect.

The main lens or mirror produces a virtual image of the obect being looked at, and it occurs at a distance behind the lens (or in front of the mirror) equal to the focal length.

The telescope also has an eyepiece whose function is to allow the oberver to see the virtual image. Many telescopes come with a range of different eyepieces that give different amounts of magnification.

The focal length of a telescope is directly related to the magnification in that the longer the focal length, the more magnification you get from the telsceope. How the focal length of a telescope relates to the length of the telescope itself depends on the design of the telescope. In a refracting telescope, the focal length is approximately the length of the telescope. In a reflecting telescope, the focal length is roughly two time the length of the telescope.

The primary mirrors of each of the two telescopes are 10 meters (33 ft) in diameter. A human eye has a pupil less than 8mm in diameter. The area of a Keck mirror is about 1,6 million times larger than that of the human pupil. (The sensors used are more sensitive too able to detect single photons).

There are hundreds of progressive lenses (also known as multi-focal or vari-focal lenses) available and they vary in price massively. The price mainly depends on the type of "design" of the progressive lens surface. Older style "conventional" progressives lenses are made using semi finished blanks. A semi finished blank is a lens which is already half made. The progressive (graduated) lens surface has already been ground onto one side of the lens. This is the part where all of the channels/corridors and reading additions are ground. An example of one of these lenses is a Hoya Summit Pro or an Essilor Varilux Comfort lens. With a conventional progressive lens, when your glasses are ordered, the lens laboratory will grind your prescription onto the other side of a semi finished blank. The wearer may find that they will be aware of distortions when they rotate their eyes to look away from the center of the lenses. Because of these problems, new lenses have been developed to reduce these optical errors (perceived by the wearer as distortions). "Free form" lenses have been designed to compensate for the errors. This means that the lens manufacturer takes into account the eyes rotation and tries to correct the errors that usually occur at every pin point on the lens surface. This technology is usually ground onto one side of the lens only but the lab will still use a semi finished blank to make the lenses. An example of one of these lenses is a Hoya iD LifeStyle (formerly called an "FD") lens. There are also lenses available which are completely customised to suit the wearer and they will be made completely from scratch without using a semi finished blank. They will also compensate for the optical errors at every point on the lens but this will be done on both sides of the lenses. This type of lens is the best option for any progressive lens wearer but it is also the most expensive. An example of one of these lenses is a Hoya iD Classic (formerly called an "iD") lens. Another thing that can effect the price is the lens material and any coatings or extra options such as transitions.

Reflecting telescopes are designed to have a curved lens which allows for objects further away to be seen clearer. For this reason astronomers and other individuals that study outer space use reflecting telescopes.

None. The megapixels are in the detecting device. e.g. a camera, a CCD device.

what is a keck telescope; The world's premier optical telescope, located on Mauna Kea in Hawaii. Completed in 1992, it is the first of a new generation of telescopes in which electronic controls constantly adjust a collection of small mirrors to compensate for atmospheric distortion to produce images of unprecedented clarity.

not much. For a telescope to be useful at 525x power it would have to be 250mm and you would need very good atmospheric conditions (a rarity). A 70mm telescope can be used at about 100x provide it is a high quality one.

A refracting telescope uses a lens (or for most refractors today, 2 or more lenses) to bend the wavelengths of visible light to a focal point as a means of collecting light. The light is then focused using an eyepiece. Depending on the focal length of the eyepiece, the effective magnification of a telescope can be altered.

Refractors and reflectors. One should add the largely Russian-developed Cassegrainean combines features of both systems-called also Maksutov after its Russian inventor who was awarded the Staliln Prize for this feat. They are adapted to (Mirror=Lens) telephoto camera lenses, also.
