Moving or variable-temperature air above or inside the telescope which distorts the image.
The spectrum analyzer is used to do distortion analysis to the signal. Due to the fact that we don't have a pure generated signal. In reality, there must be some distortion. The distortion analysis is important in the communication field as well as in electronics.
This can be done with an Equalizer. ANSWER: Not an equalizer for sure not unless the distortion is frequency related.
A:class 'a'
distortion refers to any deviation in any parameter like amplitude,time shape of an electrical signal from an ideal input signal.the distortion occurs due to the inherent non-linear characteristics of the component and devices that form the electronic circuit cause some harmonics to take place in the waveform and resultant deviation is know as harmonic distortion.
aperture distortion,it occurs due to flat top sampling. when the flat top sampling are observed through a finite duration rather than infinitisimal time is called aperture distortion.
adaptive optics
Adding a delay before distortion in a signal chain can create a more pronounced and defined distortion effect, while adding a delay after distortion can create a more spacious and atmospheric sound.
They only look: 'pointy' due to; atmospheric distortion. Stars are actually a type of 'oblate' spheroid.
Because there is less atmospheric distortion at higher altitudes, and light pollution is avoided.
Stars appear pointy due to atmospheric distortion when viewed from Earth. The Earth's atmosphere causes light from stars to bend and twinkle, making them seem to twinkle and appear pointy. In reality, stars are spherical in shape like our own sun.
The Hubble Space Telescope is located above Earth's atmosphere, which eliminates the distortion caused by atmospheric turbulence. This allows for sharper and clearer images with higher resolution compared to ground-based telescopes. Additionally, Hubble can observe wavelengths of light that are blocked by the atmosphere, providing a more comprehensive view of the universe.
Ideal weather conditions for stargazing include clear skies with minimal light pollution, low humidity to reduce atmospheric distortion, and stable atmospheric conditions to minimize twinkling of stars. Additionally, cooler temperatures can help improve visibility by reducing heat distortion.
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.

The Hubble telescope is different from land based telescopes in that being in space it does not suffer atmospheric distortion, thus clearer pictures.
The four types of distortion in maps are shape distortion, area distortion, distance distortion, and direction distortion. These distortions occur due to the challenge of transferring a three-dimensional surface onto a two-dimensional map.
They are not affected by the diffraction ("twinkling") caused by light travelling through the earth's atmosphere. Also, orbiting telescopes are not affected by atmospheric dust pollution nor light pollution.
