WebUnder typical seeing conditions, the coherence cell size r0 is from 8 to 15 cm, with seeing conditions degrading as r0 becomes smaller. When r0 = 15 cm, the seeing disk diameter will be about 1 arcsec. The parameter r0 improves with wavelength to the exponent 6/5, making turbulent blurring a nonissue at infrared wavelengths longer than 10 μm. WebCredit: NSO.
