Image of M13 from an anonymous source
The famous globular cluster M13 in Hercules, seen in a blue-light image
taken with the Lowell Observatory 1.1-meter telescope. The nonlinear
intensity mapping simultaneously shows stars with a wide brightness range,
from the brightest red giants down to the main sequence.
