| Abstract | CCD photometry of 9 RR Lyrae stars in the LMC globular cluster NGC 2210 suggests that the true distance modulus of the LMC is 18.42±0.10 mag, assuming V>RR = 0.60 and E(B-V) = 0.060 for NGC 2210. The implications of this result on the Cepheid distance scale are discussed. The results demonstrate that high-accuracy photometry on stars as faint as 20 mag is possible with a combination consisting of a CCD camera and a 1-m telescope. |
