Abstract: In this work from processed the spectra of the NGC 246 and NGC 7293 planetary nebulae we have determined the fluxes in the Hβ and HeII emission lines. Spectra of these planetary nebulae were taken from the archive of the European Southern Observatory. From the determined fluxes we calculated Zanstra temperatures according to the HI and HeII lines of the central stars of planetary nebulae. Respectively, the temperatures of 53723.14 K and 100871.43K were found for the central stars of NGC 246, the temperatures of 51072K and 89073.4K were found for the central stars of NGC 7293. The results obtained were also compared with results of other authors.
