cds-question@unistra.fropen-star-clustersccd-photometryCCD observations in B, V and I passbands have been used to generate deep V, (B-V) and V, (V-I) colour-magnitude diagrams for the open cluster NGC 7510. The sample consists of 592 stars reaching down to V=21mag. There appears to be non- uniform extinction over the face of the cluster with the value of colour excess, E(B-V), ranging from 1.0 to 1.3mag. The law of interstellar extinction in the direction of the cluster is found to be normal. A broad main sequence is clearly visible in both colour-magnitude diagrams. From the bluest part of the colour-magnitude diagrams, the true distance modulus to the cluster has been estimated as 12.5+/-0.3mag and an upper limit of 10 Myr has been assigned for the cluster age.1991MNRAS.250..683Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/250/683CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/115/325 : UBV photometry in the cluster NGC 7510 (Barbon+, 1996)J/A+A/443/157 : CCD photometry in 6 open clusters (Paunzen+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/250/683https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/250/683http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/250/683https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/250/683https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/250/683http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/250/683GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/250/683/table3 (Relative positions and CCD BVI magnitudes of stars measured in the field of NGC 7510)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/250/683/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/250/683/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/250/683/table3?GETtext/xml+votable180.050000true347.674834460.54854190.0055555555555555566/14310https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/250/683?format=asciiOpticaldefaultJ/MNRAS/250/683/table3Relative positions and CCD BVI magnitudes of stars measured in the field of NGC 7510_RAPosition computed from a comparison with 2MASS catalog II/246 ({sigma}=0.2'') (right ascension part)degpos.eq.ra;meta.main_DEPosition computed from a comparison with 2MASS catalog II/246 ({sigma}=0.2'') (declination part)degpos.eq.dec;meta.mainrecnoRecord number assigned by the VizieR team.
