cds-question@unistra.frglobular-star-clustersvariable-starsapparent-magnitudeWe present V, I photometry of the loose star cluster NGC 6749, and for the first time colour-magnitude diagrams are provided. We confirm that it is a globular cluster and its blue horizontal branch indicates that it is metal-poor. We derive a reddening of E(B-V)=1.39+/-0.04 and a distance from the Sun d_{sun}_=7.3+/-0.9kpc (assuming a total-to-selective absorption R=3.4). The cluster is projected very close to the Galactic plane, and the derived distance implies a Galactic coordinate Z~-300pc. It is thus a halo globular cluster located close to the disc plane. We also discuss the properties of 78 newly discovered long-period variable stars, of which 75 are Miras, projected within 1{deg} of the cluster centre. The variables do not appear to be associated with the globular cluster. From their periods, most of them belong to the metal-rich disc or bulge stellar populations.1997MNRAS.289..745Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/289/745CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/other/IBVS/5187 : Red variables near NGC 6749 (Skiff, 2001)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/289/745https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/289/745http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/289/745https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/289/745https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/289/745http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/289/745GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/289/745/table3 (Mira variables in the NGC 6749 field)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/289/745/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/289/745/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/289/745/table3?GETtext/xml+votable180.050000true285.903632.626490.0055555555555555566/30322-30323 30326-30329 30332-303342.367228618189496e-19 2.6706780932288093e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/289/745?format=asciiOpticaldefaultJ/MNRAS/289/745/table3Mira variables in the NGC 6749 fieldrecnoRecord number assigned by the VizieR team.
