Title The Color-Magnitude Diagram of the Globular Cluster M14
Journal Journal of the Southeastern Association for Research in Astronomy
Year of publication 2012 (on gclusters from 2015-01-09 10:17:12 )

Abstract Using the SARA 0.9 meter telescope at Kitt Peak National Observatory (KPNO) we obtained R images during the summer of 2010 and V images during the summer of 2012 of the globular cluster M14 (...) We find considerable spread in both the magnitudes and color of the RR Lyrae stars indicating a significant amount of differential reddening on relatively small scales. This is also seen in the giant branch which shows up to a ˜0.15 magnitude spread in V-R color. We also found the median magnitude of the RR Lyrae stars and hence the horizontal branch to be V=17.2.
