See all on Wikipediahttps://en.wikipedia.org/wiki/Astronomical_seeingIn astronomy, seeing refers to the degradation of the image of an astronomical object due to turbulent airflows in the atmosphere of Earth that may become visible as blurring, twinkling or variable distortion. The origin of this effect are rapidly changing variations of the optical refractive index along … See more
Astronomical seeing has several effects:
1. It causes the images of point sources (such as stars), which in the absence of atmospheric turbulence would be steady Airy patterns produced by diffraction, to break up into … See more
The first answer to this problem was speckle imaging, which allowed bright objects with simple morphology to be observed with … See more
There are three common descriptions of the astronomical seeing conditions at an observatory:
• The full width at half maximum (FWHM) of the seeing disc
• r0 (the size of a typical "lump" of uniform air within the turbulent atmosphere ) and t0 … See more• Atmosphere and Telescope Simulator, a simulator of atmospheric turbulence

Astronomy (from Ancient Greek ἀστρονομία (astronomía) 'science that studies the laws of the stars') is a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, and comets. Relevant phenomena include supernova explosions, gam…
