Hubbard Scientific Glow-in-the-Dark Seasonal Star Chart Book Review

These star maps have been sold under various names (Hubbard, Celestron, etc.) for decades, but they all seem to have the same origin. A reviewer of another version claims that some of the data (distances, magnitudes, etc.) do not agree with other sources. Also, there are some obvious typographical errors. Thus, I would not rely on these charts as a primary source of astronomical data. (For example, we don't call M31 the "Great Nebula" anymore, it's the Andromeda Galaxy.)

However, with that understanding, these charts are very good for people learning the sky. While there are iPad apps, planetarium programs for laptops, and more, sometimes a printed chart and a red flashlight are just easier. These charts are very easy to read. They show all of the naked eye stars that would be visible at a reasonably dark location. Many prominent deep-sky objects and numerous double stars are listed by constellation. The planisphere (rotating chart) on the cover shows you what constellations are visible on any given evening. Note that in a city, the light pollution may obscure many of these stars, making the charts less useful. But, if you can get away from town, particularly if you have binoculars or a telescope, you will find these charts very helpful.

Note: these charts are useful in the Northern Hemisphere only! Do not buy if you want to use them in the Southern Hemisphere.
