Simply dial in the time of the day and the day of the year on this handy rotating disc star chart to see exactly how the sky will appear overhead at that particular moment. It works for any hour, of any day, of any year. You can use it to learn the constellations, or to easily and quickly determine when a particular part of the sky will be visible, so you can plan your observing sessions in advance. This Planisphere shows more than 1000 stars to the fifth magnitude and lists many star names. It shows light stars on a dark background, 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 naked eye from dark sky sites. The Miller Planisphere is made of heavy-duty washable plastic and is unaffected by dew and moisture, so it will remain readable and useful for years to come. It’s complete with a protective plastic slipcase. This 50 degree North Planisphere is for use at observing sites from 45 degrees north to 55 degrees north, which covers the far northern United States and southern Canada (Seattle, Calgary, Quebec, etc.)
