cds-question@unistra.frglobular-star-clustersvisible-astronomybroad-band-photometryPhotometry of NGC 7492, a very faint, well resolved cluster, shows that it has a colour-magnitude relation similar in form to that of a typical globular cluster. A well defined but sparsely populated red giant branch is present, along with a horizontal branch, blue stars, and variables. The distance modulus, 17.17, and the distance 27.2kpc., are obtained. The colour excess appears to be negligible. The integrated photographic absolute magnitude is -4.84. The star density in the cluster is unusually low, being approximately 0.06 stars per cubic parsec for stars brighter than +2.5 absolute magnitude.
