In the June 2023 issue of Sky & Telescope, we have a beginner’s guide to photographing the summer Milky Way. And for deep-sky astrophotographers, we teach you the basics of using PixInsight, a popular astronomical image-processing software. Last on our photography agenda, the Celestial Sleuth Don Olson breaks out his magnifying glass and telescope to figure out the date Ansel Adams captured two famous photographs of Yosemite National Park. Next, we dive deep into the Milky Way’s starry depths, searching for the farthest globular clusters we can see from Earth. Also in this issue, we explore the differences between comets and asteroids, which it turns out are not as cut and dry as we once thought. We’re now starting to understand how asteroids can sometimes form cometary tails, too.
