What limition of a refracting telescope could be overcome by placing the telescope in space?
If the telescope were placed in space (like hubble) the images would be greatly improved due to the lack of both atmosphere and ambient light, such as streetlights. The lack of atmosphere means that the light from distant objects need not travel through turbulent gases found in the atmosphere. this would eliminate the 'twinkling' of stars, and the lack of ambient light would result in much greater detail in the image.

What limitation of a refracting telescope could be 'overcome by placing the telescope in space?
If the telescope were placed in space (like hubble) the images would be greatly improved due to the lack of both atmosphere and ambient light, such as streetlights.

What are two ways in which astronomers can overcome the distortion of starlight that is caused by the earths atmosphere?
Astronomers can overcome the distortion of starlight caused by Earth's atmosphere by using adaptive optics, which involves real-time adjustments of telescope mirrors to compensate for atmospheric turbulence. Another method is placing telescopes in space, such as the Hubble Space Telescope, which eliminates atmospheric interference altogether, allowing for clearer and more detailed observations of celestial objects.
Who came up with the idea to have a telescope orbiting the earth?
The idea of placing a telescope in orbit around the Earth was popularized by American astronomer Lyman Spitzer in the 1940s. He proposed the concept of a space telescope to avoid atmospheric distortion, which hampers ground-based observations. This idea ultimately led to the development of the Hubble Space Telescope, launched in 1990.
Why did astronomers want to put a telescope into space?
Astronomers wanted to put a telescope into space to avoid the distortion caused by Earth's atmosphere, which can affect the quality of images taken by ground-based telescopes. By placing a telescope in space, astronomers can achieve sharper and clearer images of celestial objects.
What are the benefits of placing an optical telescope in the middle of the countryside?
Placing an optical telescope in the countryside offers several benefits, primarily due to reduced light pollution, which enhances the clarity and quality of astronomical observations. The rural environment typically has less atmospheric turbulence and fewer obstructions, leading to improved visibility of celestial objects. Additionally, the isolation from urban infrastructure minimizes disturbances from human activity, allowing for longer, uninterrupted observation sessions. Lastly, the natural surroundings can provide a more stable and cooler environment, which is beneficial for the telescope's sensitive equipment.
Who invented the submarine telescope?
The submarine telescope was not invented by an individual but rather refers to a scientific concept of placing a telescope in an underwater observatory to observe celestial objects. This concept is still being developed and researched by scientists and engineers.
How did Newton solve the problem of using an eyepiece with a reflecting telescope?
== == Newton did not invent the reflecting telescope. The first reflecting telescope is credited to Niccolò Zucchi in 1616. In 1668, Isaac Newton made significant improvements to the design resulting in a much improved reflecting telescope that still bears his name, the "Newtonian reflector." He did it because the refracting (lens) telescopes of the day suffered severe color aberration. (Different focal lengths of different colours of light resulting in a blurred image because all the colours can't be brought into focus at the same time.) Reflecting telescopes do not suffer from color aberation and Newton's improvements made them effective observing instruments. Although the colour aberration of refractors was partially solved by the invention of the achromatic lens in 1733 Newton's design remains in use to this day.
The LEAST desirable location for an optical telescope is likely to be?
Near a city or urban area due to light pollution and air pollution, which can severely impact the quality of observations. Additionally, placing a telescope in a region prone to frequent cloud cover or atmospheric disturbances would also be undesirable.
Would it make sense to place an X-ray or gamma ray telescope on a mountain top?
Yes, placing an X-ray or gamma ray telescope on a mountain top can reduce atmospheric interference and provide clearer observations due to the thinner atmosphere at higher altitudes. This can improve the sensitivity and accuracy of the telescope in detecting these high-energy emissions from space.
How do you columnate a schmidt-cassegrainian telescope?
There are usually 3 adjusting screws on the front of the telescope over the secondary mirror. You point the telescope at a bright star and then defocus it this forms a donut-like image in the telescope. If you center the "doughnut" in the middle of the telescope view you will see that the "doughnut" has the dark area in the middle off center (If the scope is not colminated properly). What you want to do is move the doughnut to the edge of the telescope in the direction where the dark center is "out of center". Now you will tighten one of the three screws in the front. The way to figure out which screw to adjust is by placing your finger in front of the scope where the doughnut is out of center. You will see a dark line in the doughnut image where your finger is and it will actually be pointing to one of the three screws in front - that screw needs to be tightened. You repeat these steps until when you put the dougnut in the center view of the telescope and see a perfect looking "doughnut" with the dark part centered perfectly.

Would it make sense to place an x-rays or gamma ray telescope on a mountaintop?
Placing an x-ray or gamma-ray telescope on a mountaintop can have advantages due to reduced atmospheric interference at higher altitudes, allowing for clearer observations of these high-energy wavelengths. However, mountaintop locations may also face challenges such as accessibility, logistical issues, and environmental concerns. Ultimately, the decision would depend on the specific scientific goals of the telescope and the trade-offs between atmospheric interference and operational constraints.
