cds-question@unistra.fropen-star-clustersccd-photometryWe report CCD B and V photometry for the central region of the old open cluster NGC 7762. The cluster appears very loose and occupies a large sky area. The Colour Magnitude Diagram (CMD) shows a distinct Main Sequence (MS) down to V=~16.5, and a couple of evolved stars. The bottom of the sequence is characterized by a large spread, much greater than the expected broadness due to photometric errors, and probably related to low mass stars evaporation. The analysis here carried out allows us to conclude that NGC 7762 in an intermediate age cluster about 1.8Gyr old. The comparison with theoretical isochrones from the Padova group constrains colour excess and apparent distance modulus in the range 0.85-0.90 and 12.00-12.20, respectively. The distance to the Sun comes out to be 800 pc, somewhat lower than Chincarini's (1966MmSAI..37..423C) estimate.1995A&AS..114..281Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/114/281CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/114/281https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/114/281http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/114/281https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/114/281https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/114/281http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/114/281GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+AS/114/281/table2PhotometryrecnoRecord number assigned by the VizieR team.
