Fast note on Wien’s law

Just a quick reminder* ! λmax = 2.89776829 x 106 nm K / T [*] Wien’s displacement law

Selected sky lines

A list of sky lines that can be found in spectra (read … handy sky lines!): wavelength (in Å): 5577.3 ( > 5579) 5893 ( > 5890, 5896) 6300.3 6363.8 (1/3 of 6300.3) An excellent and very convenient tool to find and plot the sky lines from 3140 – 10430 can be found at vizier, […]
