Book Description

January 1, 1998 0961320753 978-0961320751 Large Plastic 30-40 degrees Edition
The Night Sky is a rotating star finder (planisphere) that allows the user to recognize the constellations for any time of night, any day of the year. The sky appears to rotate (due to the rotation and orbital motion of the earth), so to be successful recognizing the constellations a beginner needs to know which stars are above the horizon at any time.

This is the full-sized version of The Night Sky suitable for the 30°-40° latitude zone (southern half of the US, North Africa, Middle East, etc.). There are editions for the following latitude zones: 50°-60°, 40°-50°, 30°-40°, 20°-30°, and the Southern Hemisphere. There are also pocket-sized versions available for the same latitude zones.

Editorial Reviews


Chandler's planisphere is the finest available. -- Terence Dickinson, astronomy textbook author, in SkyNews Magazine --Terence Dickinson

I think The Night Sky is the finest and easiest to use star finding aid in existence. -- Jack Horkheimer, TV's Star Hustler. --Jack Horkheimer

Most aficionados now prefer David Chandler's The Night Sky wheel. -- J.T. Westways Magazine --Westways Magazine

From the Publisher

The Night Sky comes in two sizes: Large (8 inch diameter) and Small (5 inch diameter). The large size is best for learning the constellations. The small size is best as a pocket reference to tell you what constellations are up if you are already reasonably familiar with the constellations. In each size the charts are available for different latitude zones.

To find the correct size and latitude zone, use the following ISBN numbers in your search:

The Night Sky 50°-60° (Large), 1891938088 (Small), 1891938096

The Night Sky 40°-50° (Large), 0961320745 (Small), 1891938010

The Night Sky 30°-40° (Large), 0961320753 (Small), 1891938029

The Night Sky 20°-30° (Large), 0961320761 (Small), 1891938037

The Night Sky Southern Hemisphere (Large), 0961320737 (Small), 1891938002

5.0 out of 5 stars A useful tool- convenient; practical; durable. February 19, 2001
A rotating starfinder like this one (often referred to as a "Planisphere") effectively shows how the night sky looks at any given time on any night of the year. For instance, if it's 10 p.m. on April 30th, just line up April 30th on the outer wheel with 10 p.m. on the inner wheel. The starfinder will thus display the position and orientation of the constellations that are visible to you at that time. As time passes, celestial objects "drift" from east to west due to the Earth's rotation. Occasional adjustment (rotating the planisphere's inner wheel to keep up with passing time) will sustain an accurate representation. As with any night-time observing aid, it should be viewed with red light.
Planispheres are generally manufactured in incremental versions to accommodate various bandwidths of latitudes from which to use them. For northern latitudes they are most commonly offered in 20/30; 30/40; and 40/50-degree versions. The Night Sky "30-40" matches latitudes from 30 to 40 degrees North, i.e.: - the mid-southern United States. You should select the one that brackets your particular latitude.
Classic boundaries of the constellations are highlighted with lines connecting principal stars down to 5th magnitude. A few of the more significant celestial objects are represent as well, i.e.: - M31. Right Ascension and Declination scales are provided. The front side shows the sky as you face north. Turning the planisphere over (from front to back) shows the sky as it looks facing south - and without distortion.
A good starfinder is a useful tool, and Chandler's Night Sky planisphere has become my personal favorite. It makes for a good learning device as well, and is the planisphere of choice for Terrence Dickinson ("The Backyard Astronomer's Guide").

5.0 out of 5 stars Star gazing February 6, 2007
Superb product. The prduct is made of sturdy material(plastic?) not like the cardboard one I owned in the past. I love the clear plastic cover which can keep the dew and my fingerprints at bay. The chart itself, in addition, to the constellations locates Messier objects and nebulae.

This is great item to take on a camping trips or just stash in the glove compartment for impromptu stops to see the stars.

Make sure you buy the chart that is at or near the latitude where you live. The USA runs from 30-50 degrees latitude. So if you live at or south of New York and Denver then get the 30-40. If much above that, get the 40-50 degree latitude

5.0 out of 5 stars Best In The Night Sky January 4, 2007
Format:Map|Verified Purchase
After much careful comparing I found this Plainesphere to be the best one out there. Has a back side which is actually useful. I bought 2 as Christmas gifts and were enthusiastically received. Highly recommended.

By the way - also get a Red LED flashlight to go with these to preserve night vision. Amazon has a great small one at a good price.

5.0 out of 5 stars New Astronomer's Best Friend April 15, 2009
As an astronomy enthusiast for over 40 years, and now an astronomy professor, I'm often asked "How do I know what I'm looking at?" or "How do I find constellations like the Big Dipper or Orion?" The answer for every beginner is to use a good planisphere - a rotating star map that shows you what the stars and constellations look like from your location at any time of night, any night of the year. The rotating star map - the planisphere - does this easily and without any effort. If you can tell time, and you know what day it is - you can use this product easily! Everyone from children as young as 7 years old to college students find this to be a user friendly way to learn the sky.
Chandler's planisphere is a step above most others because it has very little distortion - the shapes of constellations on the map are the same as they appear when you see them in the sky (very important for new or younger astronomers!) The Chandler map is also rugged enough to withstand years of use - I have classroom models that have been in use for 10 years and more.
Be sure to get the right version for where you live! The 30-40 degree model covers northern Mexico through the central USA. Northern US and Canada will need the 40-50 degree version.

4.0 out of 5 stars Good planisphere August 16, 2005
Actually I would give this planisphere a rating of 3.5 rather than 4. It is a good planisphere overall. The plastic it is made of is of good quality & it comes in a plastic cover for storage. Instructions are printed on one side for the beginner, and they are brief yet very explanatory. Blue ink against a white background make this planisphere very easy to read under filtered red light since the blue appears black under red light. However, I find it lacks detail. Although all constellations are on it, only a few Messier objects are plotted. I've seen other planispheres with much more detail. Another thing it lacks is a list of the planets & when they are best viewed. I've seen this list on many other planispheres, but not on this one. The bottom line, however, is that this is a very good planisphere for those beginners who want to learn well the constellations.

By A Customer
Dave Chandler's Night Sky has been a useful toll for me for many years of comet hunting. I began using it 20 years ago to determine what stars I should be seeing near the horizon at the evening and morning twilights. It is very simple to use, both during the day and at night.

Which one is better for NYC. 30-40 or 40-50 star wheel?
NYC is right on 40 North. Depends on where you will be using it most....will your observing site have the best view to the south, or to the north?

South - Go with 30-40
North - Go with 40-50

Both will work perfectly well for you.
