Zoom Into May: Jupiter, Betelgeuse & Dragonfly Eyes

Find inspiration in the May issue of Sky & Telescope, where we feature awe-inspiring, amateur-processed images of the king of planets, an in-depth study of Betelgeuse — the star most likely to go supernova (or is it?) — and a look behind the scenes of the Dragonfly project, where astronomers built an insect-eyed telescope from off-the-shelf equipment. The skies are bright with promise, as Jupiter and Saturn are approaching their oppositions. Meanwhile, the brightest dwarf planet, Ceres, is on display as it reaches opposition at the end of May. The May issue also includes a Test Report on the new Omegon Mini Track LX2, which provides no-frills sky tracking, and a look at a Raspberry Pi-based camera controller.

Enjoyed reading Steve Gottlieb's Going Deep column: "The Billion Light-Year Club." Gave my wrinkled old brain a real workout 🙂
