With a rotating star chart to help you locate constellations at any time of the night throughout the year, and a small flashlight covered with some red cellophane, you're fully equipped to go out and stargaze. (The red cellophane stops your eyes having to readjust to the low level of light in the binoculars after looking at the chart.)
除了雙筒望遠鏡，再添購一個最佳天文小老師──旋轉星座盤，只要對準日期與時間按圖索驥，就能告訴你一年三百六十五天每晚每時可見的星空；外帶一個包著紅色玻璃紙的小電筒，以便在漆黑處看清星座盤，如此，出門觀星的工具已然備妥。
