Deep sky challenge: A Gaggle of glittering globular clusters

Messier 13 isn’t the only stellar gathering to see in the early summer sky

As spring slides into summer, the brightness of the night sky makes observing deep-sky objects quite a challenge. The misty nebulae and smoky galaxies that fill our eyepieces on the long, frosty nights of darker seasons become washed out by the lingering twilight. Fortunately, there are plenty of other deep-sky objects to track down and observe, like globular clusters.
