With this Planisphere from Astronomy magazine, you can learn the constellations, or easily and quickly determine when a particular part of the sky will be visible from your observing site, so you can plan your observing sessions in advance. Simply dial in the time of the day and the day of the year on this handy rotating disc star chart and its sky window will show you exactly how the sky will appear overhead at that particular moment. It works for any hour, of any day, of any year.

This 10.5” diameter Planisphere shows more than 1,000 stars to the fifth magnitude and lists many star names. It shows light stars on a blue background to protect your dark-adapted vision, and shows the Milky Way, constellation outlines, and stellar magnitudes. On the back is a list of the constellations in which the major planets will appear over the next few years. It also shows the positions of the brighter Messier objects, including all those visible to the unaided eye from a dark sky site.
