A valuable tool for novice and advanced stargazers.
The 30 x 30 cm Firefly Planisphere is an affordable, practical tool for accurately locating night sky phenomena in the Northern Hemisphere at any time of the year -- and is now updated to include planetary tables from 2007 up to and including 2014
Charted by the month, day, hour and minute, it gives quick help on locating celestial wonders such as:
• Globular clusters
The easy to use Firefly Planisphere features:
• Icons that describe star magnitudes from O to 1 (large) to 4(small). The larger the symbol, the brighter the star -making it easy to locate specific stars.
• Updated planetary tables with at-a-glance coordinates for locating the brightest objects in the sky until 2014.
• Times of sunrise and sunset for each day.
An easy-to-read instructional guide describes how to use the planisphere. Both the planisphere and the guide are packaged in a protective plastic envelope.
