N. Abstract New CCD photometry of the halo globular cluster NGC 2298 is used to construct BV and VR color-magnitude diagrams. Photoelectric UBV photometry of stars in the cluster region indicates a reddening value of the order of 0.20, and a comparison of the cluster with five other clusters of similar metallicity (M68, NGC 5024, NGC 5053, M92, and M15) leads to values of E(B-V) = 0.18 and (m-M)V = 15.45. The color-magnitude diagrams of NGC 2298 and the five comparison clusters are virtually identical; when their main sequences are matched, the giant and horizontal-branch regions are aligned within the (small) photometric uncertainties. However, using the derived value for the reddening to NGC 2298, the cluster cannot be matched to published theoretical isochrones without an additional color shift.
