A planisphere and sky charts are essential tools for night-sky viewing. Having a reliable planisphere on hand is the best way for stargazers to be sure they do not miss any celestial phenomena, especially the rare ones.
On any day of the year, the Firefly Planisphere will help a stargazer locate night-sky events quickly. Charted by the month, day, hour and minute, it gives help on locating celestial wonders such as planets, stars, constellations, globular clusters, nebulae and galaxies.
It includes icons that describe star magnitudes, planetary tables with at-a-glance coordinates for locating the brightest objects in the sky and the times of sunrise and sunset for each day.
This edition has been updated and includes planetary tables through to 2015. It is made of laminated plastic for durability and comes inside a protective plastic envelope.
