Can the temperature of clouds on Neptune be measured using Wien's Law? As an example, if the maximum wavelength of emission from Neptune's clouds is 6.0 x 10 Exp-5 would the Temperature be 48.33K? Or does the blackbody principle requirement of Wien's Law not work in this case?

More likely the distribution of frequencies would be fitted to Planck's radiation formula to obtain a more accurate measure of the average temperature. But what one obtains is a temperature averaged over the entire field of view.
