cds-question@unistra.frplanetary-nebulaegalaxiesphotometryvisible-astronomyspectroscopyeffective-temperatureWe perform a deep survey of planetary nebulae (PNe) in the spiral galaxy NGC 300 to construct its planetary nebula luminosity function (PNLF). We aim to derive the distance using the PNLF and to probe the characteristics of the most luminous PNe. We analyse 44 fields observed with MUSE at the VLT, covering a total area of ~11kpc^2^. We find [OIII]5007 sources using the differential emission line filter (DELF) technique. We identify PNe through spectral classification using the aid of the BPT-diagram. The PNLF distance is derived using the maximum likelihood estimation technique. For the more luminous PNe, we also measure their extinction using the Balmer decrement. We estimate the luminosity and effective temperature of the central stars of the luminous PNe, based on estimates of the excitation class and the assumption of optically thick nebulae. We identify 107 PNe and derive a most-likely distance modulus (m-M)_0_=26.48^+0.11^_-0.26_ (d=1.98^+0.10^_-0.23_Mpc). We find that the PNe at the PNLF cut-off exhibit relatively low extinction, with some high extinction cases caused by local dust lanes. We present the lower limit luminosities and effective temperatures of the central stars for some of the brighter PNe. We also identify a few Type I PNe that come from a young population with progenitor masses >2.5M_{sun}_, however do not populate the PNLF cut-off. The spatial resolution and spectral information of MUSE allow precise PN classification and photometry. These capabilities also enable us to resolve possible contamination by diffuse gas and dust, improving the accuracy of the PNLF distance to NGC 300.2023A&A...671A.142Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/671/A142CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/547/A78 : Catalog of NGC 300 planetary nebula candidates (Pena+, 2012)J/A+A/618/A3 : NGC 300 MUSE spectroscopy for central fields (Roth+, 2018)J/A+A/668/A74 : NGC 300 catalog of HII and DIG regions (Micheva+, 2022)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/671/A142https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/671/A142http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/671/A142https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/671/A142https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/671/A142http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/671/A142GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/671/A142/tabled1 (Catalogue of 107 planetary nebulae based on the observation of 44 MUSE fields in NGC 300 (Updated version from the author))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/671/A142/tabled1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/671/A142/tabled1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/671/A142/tabled1?GETtext/xml+votable180.050000true13.701835556-37.6634438890.0055555555555555566/35536 35538https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/671/A142?format=asciiOpticaldefaultJ/A+A/671/A142/tabled1Catalogue of 107 planetary nebulae based on the observation of 44 MUSE fields in NGC 300 (Updated version from the author)recnoRecord number assigned by the VizieR team.
