As seen on BBC!

A practical and convenient hour-by-hour tracker of the stars and constellations. This invaluable tool has informed and educated generations of astronomers - (I have a battered and abused one that dates from the 1970s and it still gets regular use).

Made of sturdy plastic with "reminder" instructions printed on the rear - Please note the disposable packaging that this product is supplied in (shown in the picture) can vary and may be different to that shown.

Much quicker and convenient to use than planetarium software on a computer - the great strength of the Planishere is that it can be used outside and direct comparisons can be made holding the Planisphere up agaist the sky to identify stars and other targets. Ideal for identifying constellations, the Planishere also has a useful table printed on the back that gives the positions of Venus, Mars, Jupiter, and Saturn until 2020. Sunset and sunrise times can be predited as well as the rise,set and high transit time (the point when an object is highest in the sky and best placed for observation or imaging) of stars and other targets.
