What are the advantages and disadvantages of using different telescopes for astronomical observations?
Advantages of using different telescopes for astronomical observations include the ability to observe different wavelengths of light, which can provide more information about celestial objects. Additionally, different telescopes have varying levels of resolution and sensitivity, allowing for more detailed and accurate observations. Disadvantages include the cost and maintenance of multiple telescopes, as well as the need for specialized knowledge to operate each type effectively. Additionally, using different telescopes can lead to inconsistencies in data collection and analysis.
What are the disadvantages of telescopes?
Some disadvantages of telescopes include limited field of view, susceptibility to atmospheric conditions such as turbulence and light pollution, and the need for regular maintenance and calibration to ensure optimal performance. Additionally, high-quality telescopes can be expensive and may require specialized expertise to operate effectively.
What telescope uses an eyepiece and an objective lens?
Practically all telescopes which use lenses, normally the refracting type. the Reflector use objective Concave Mirrors, but even these need eyepieces or finder scopes.
Why do most professional astronomers use reflecting telescopes?
Bang for the buck. When you need to collect a lot of light to see faintcelestial objects clearly, a large mirror is cheaper and easier to manufacture without defects than asimilarly sized refracting lens.
What are the 5 main main telescopes used to gather information about the universe?
Optical (refracting and reflecting types), Radio, Infra-red, X-ray, Gamma-ray. Some of these need to be carried on satellites as the atmosphere absorbs the radiation under study - fortunately for us!
Why do cats need attention?
Cats need attention for mental stimulation, social interaction, and to feel loved and secure. Regular attention helps prevent behavioral issues and strengthens the bond between cats and their owners.
What advantages do reflecting telescopes have over refracting telescopes?
refracting telescopes use lenses instead of mirrors. 1. chromatic aberration: when light passes through a lens it is focused at different points. Blue focuses closer to lens and red farther creating a smeared image. 2. Some light is absorbed by lenses. 3. Lenses are heavy and can only be supported by the edge. 4. Lenses must have to optically acceptable surfaces whereas a mirror only needs one.
Why does my cat need constant attention?
Cats may need constant attention because they are social animals that crave interaction and companionship. They may seek attention from their owners for comfort, play, or to fulfill their natural instincts. Providing regular attention and engagement can help strengthen the bond between you and your cat.
What makes rabbits like you?
If you want a rabbit to like you, you need to give it a lot of attention, and stroke, and hold it on a regular basis.
Why do scintists use telescopes?
They need to look at the stars
Why do you need to put some telescopes in space?
Telescopes on Earth have to look through the atmosphere (air) which distorts the image. Telescopes in space dont have to look through the atmosphere and so the image is a lot clearer.
Is the Worlds largest telescope refracting or reflecting?
Large lenses deform under their own weight, but mirrors can be supported. Reflectors do not suffer from chromatic aberration like refractors do. Large mirrors need only one optical surface, achromats four surfaces to grind. Large, very clear lenses are harder to cast than more tolerant mirror blanks.
