A professional-level tool for observing the night sky.
The large 15 inch Firefly Planisphere Deluxe is a practical tool for accurately locating night sky phenomena at any time of the year. Constructed of sturdy plastic, simply turn the disks to line up the month and date, and the clear top panel reveals the actual positions of the stars. It is also useful for locating planets, stars, constellations, globular clusters, nebula and galaxies at any particular time.
The planisphere is charted by the month, day, hour and minute, so it can be used to plan future viewings. The planisphere also calculates the time of sunrise and sunset for any specific day.
An easy-to-read 24-page companion book describes how to adjust and use the planisphere. The book and planisphere are packaged in a convenient boxed set.
The Firefly Planisphere Deluxe is an indispensable tool for astronomers of all ages.
