内容简介

Here's an all-sky map that's good anytime throughout the year. The Sky and Telescope Star Wheel features the iconic SandT monthly star chart, replotted as a planisphere complete with its accurately marked star brightnesses and locations of famous deep-sky objects. The back offers a companion chart that shows a less distorted view of the sky to the south. The full-color Star Wheel is easy to read in daylight or at night under a red flashlight. It even accommodates daylight-saving time.
