La méthode de Struve et Elvey pour détecter les émissions galactiques est extrêmement sensible, mais aussi fort laborieuse, puisque l'examen de chaque région céleste exige une pose de plusieurs heures. L'invention des "filtres interférentiels", qui permettent d'isoler, sans appareil dispersif, des régions spectrales étroites, a conduit à mettre au point des méthodes plus expéditives, bien que de sensibilité comparable.
