“A work of art [that] no amateur astronomer should be without.”
— Astronomy Forum<\/p>\n

The Firefly Planisphere is a valuable tool for beginner and advanced stargazers. The previous edition, published in 2018, had star maps up to 2030. This seventh edition updates the maps to 2036. <\/p>\n

Charted by the month, day, hour and minute, the Firefly Planisphere is easy to use, battery-free and weather-resistant. The stargazer needs only to turn the wheel to align the current date and time. What the see-through panel reveals will match the view of the night sky. <\/p>\n

The planisphere shows the position of the stars for every night of the year. Icons describe star magnitudes — the larger the symbol, the brighter the star — making it easy to locate specific stars. Stargazers will be able to identify planets, stars, constellations, globular clusters, nebulas, galaxies and other celestial wonders. <\/p>\n

Features include: <\/p>\n

At-a-glance coordinates for locating the brightest objects in the sky Planetary tables to locate Venus, Mars, Jupiter and Saturn, now improved for easier use An overlay window with a new shape for better viewing Times of sunrise and sunset for each day Declination and right ascension scales The ecliptic path.<\/p>\n

The planisphere’s booklet provides accurate information on bright and faint stars, the Milky Way and deep-sky searching. Other topics include: <\/p>\n

How to use the planisphere Finding planets, sunrise and sunset How to read a star map Learning the sky Exploring the skies, season by season.<\/p>\n

With its improved features, sturdy construction, portability, weather resistance, smooth wheel rotation, easy-to-read booklet and protective pocket, the Firefly Planisphere is simply the handiest guide to the night sky for the amateur astronomer. <\/p>\n
