About this product

Generally regarded as the BEST planisphere!

This sturdy planisphere is a quick and convenient way of seeing which constellations are above the horizon at any specified time and day of the year.

Sky and Telescope magazine adopted The David Chandler 'Night Sky' planisphere in 1976 and has promoted it ever since. The amateur astronomy and educational communities widely recognise it as the best planisphere on the market.

"Chandler's planisphere (rotating star-finder wheel) is the finest available" Sky News.

Key features:

• Unlike coffee-table planispheres, The Night Sky is printed with dark stars on a light background for easy nighttime readability.
• The constellations are drawn, emphasising the brighter stars. The constellation patterns were designed in collaboration with Sky and Telescope magazine editors.
• Coordinate grid lines are shown without being intrusive. Coordinates are shown because they can be useful for cross-referencing with star atlases.
• A selection of deep sky objects for binocular viewing is included. To beginners, it is important to point out that the best first telescope is a pair of binoculars. You may already have what it takes to start observing tonight!
• The Night Sky is larger than it looks! The map scale is larger than on similar-size planispheres because the whole sky does not have to be shown on a single map.

Measures approx 8.5 x 10 inches 

Southern Hemisphere Version

The Southern Hemisphere version, covers latitudes from 20° South and greater.

Japanese Version

The latitude setting of the Japanese planisphere is 35°N, which will work well for all of Japan. This is not a crude transliteration. Every aspect of the text has been critiqued and rewritten to read naturally in Japanese by two expert amateur astronomers living in Japan. Even the constellation patterns have been altered to better conform to how they are recognised in Japan. (Sagittarius, for example, is seen as a Teapot by most Americans. However, it does not look like a Japanese teapot!)

How to use:

With The Night Sky™, you will be up and running and locating constellations within minutes.

Basic Instructions:

• Find the date on the outer edge of the rotating map dial.
• Find the time on the outer edge of the blue mask.
• Rotate the map dial to align the day with the time.
  • Use Standard Time for your location.  (If in Daylight Savings time, subtract one hour.)
• To view objects in the northern half of the sky:
  • Face North and hold the chart upright in front of you, so the word “North” on the blue mask is horizontal.  Objects near the horizon line on the planisphere will be low in the sky, near the northern horizon.
• Tilt the chart to the right or left when you face East or West, so the word “East” or “West” is horizontal.
• To view objects in the southern half of the sky:
  • Face South and, without moving the map dial, flip the chart over and hold the chart upright, so the word “South” on the blue mask is horizontal.  Objects near the horizon line on the planisphere will be low in the sky, near the southern horizon.
• Tilt the chart to the right or left when you face East or West, so the word “East” or “West” is horizontal.

Note For Southern Hemisphere Planispheres: The South side is the front, therefore, start by facing South, and hold the chart upright in front of you, so the word “South” on the blue mask is horizontal.

Tip:

To find an unfamiliar constellation or star, you can first find a bright star or familiar constellation in the sky.  Next, locate the object on The Night Sky™ planisphere and find an adjacent constellation in the direction of the new object.  Look up and attempt to find the adjacent object in the sky.  Keep using nearby constellations or bright stars as stepping stones to help find the object you seek.
