Hi All,

For those amateur astronomers into visually observing globular star clusters -- Absolute V-band magnitudes and mass-to-light ratios of galactic globular clusters. Until now, it has been difficult to find reliable, genuine V-band magnitudes for G.Cs and from that absolute magnitudes, surface brightnesses & etc.

A valuable resource.

Thanks, Les, for the link. It will be interesting to compare the new V magnitudes with traditional ones (Harris).
