Sagitta, a small constellation between Aquila and Vulpecula, features Zeta Sagittae, a fascinating triple star system. The brighter component, Zeta Sagittae A, shines at magnitude 5, while its companion, Zeta Sagittae B, is fainter at magnitude 9. Located near Altair, this hidden treasure is worth observing with a telescope. Also known as STF 2585, SAO 105298, 8 Sagittae, HR 7546, HIP 97496, HD 187362

Messier 71 (NGC 6838): A Globular Cluster Close to Home
Globular clusters like Messier 71 (M71) make for great targets. With a pair of binoculars away from bright city lights, an observer can see M71 as a fuzzy patch. Move up to the telescope (say 4 inches in diameter and larger), and you can start to make out some individual stars. For a long time,ContinueContinue reading “Messier 71 (NGC 6838): A Globular Cluster Close to Home”
