M5 is one of the oldest globular clusters, with a computed age of 13 billion
years. Its diameter is about 140 light years, making it one of the larger globular
clusters.
At its distance of 24,500 light years and contains the considerably large number
of 105 known variable stars. M5 is receding from us at about 50 km/sec.
I take this image through a Celestron refractor 102mm f/5 on Pixcel
237 CCD. Image is composite of 19x10 second unguided exposures (median combine
in CCDSoft v5).
