| Abstract: |
We have undertaken a preliminary investigation of the metal-poor low-latitude globular clusters NGC 6293 and NGC 6333 using CCD images from the University of Hawaii 2.24-meter telescope, obtained on two nights when the seeing was about 0.6 arcsec. The color-magnitude diagrams (CMDs) for the two clusters show well-defined giant branches and blue horizontal branches and reach just to the main-sequence turnoff. Their CMD morphologies resemble each other very closely as well as that of M92; a comparison of NGC 6293 and NGC 6333 with the latter yields probable reddening values of about 0.47 and about 0.44 mag and apparent distance moduli of about 16.0 and about 15.8, respectively, placing the clusters roughly 1-2 kpc from the Galactic center. |
