In this talk, Azlizan will present the planetary nebula luminosity function (PNLF) of NGC 300. The PNLF is a reliable distance indicator with ~10% accuracy, comparable with the Cepheids and the tip of red giant branch (TRGB) method. However, in star-forming galaxies like NGC 300, other ionised nebulae such as supernova remnants or compact HII regions are prone to be misclassified as planetary nebulae (PNe), reducing the reliability of the PNLF. In this context, the impressive angular resolution and spectral information of MUSE allow us to better discriminate PNe from their mimics.
