Sky & Telescope July 2021 Magazine
The July 2021 issue of Sky & Telescope is absolutely sparkling with star clusters. We’re taking a deep dive into these glittering showpieces with guides on observing and photographing the best clusters summer has to offer. Plus, we peek into their histories and the planets hiding deep inside open clusters. This issue also has several observing challenges for fans of Saturn and Pluto. And if all these sparklers aren’t enough, we’re also looking 40 years ahead to Comet Halley’s next appearance.
