We develop a simple technique to accurately measure frequency differences between far-lying resonances in a spectroscopy signal using a single, unlocked laser. This technique was used to measure the isotope shift (IS) of the cooling transition of metastable neon. Our result of 1626.287(53) MHz is the most accurate determination of this value to date.
