Rating for practical purposes 8/10, for entertainment as something to read 3/10

If you ever need to find something in the night-sky, then this book would probably help you. It has all the naked-eye objects and also the things for which you need binoculars, the latter being really the reason for the book’s existence.

It starts out with the basics, giving spectral-types and different types of variable stars. Then there’re the brightest objects you can see using binoculars for each constellation.

Reading that part reminded me of the time when I used to read English-Estonian or German-Estonian dictionaries just for fun. It stopped being fun after a couple or ten pages, and it’s a good way to remind yourself of something you’ve always wanted to do and never had the time for. Reading about all those objects was a bit like that.

Since it should be actually used more as a handbook and for example for planning observations, then it’s really useful, the charts for each constellation and how to find the constellations are helpful (reminded me that I was supposed to learn the southern constellations a while back…).

After the constellation guides, in which there are the brightest stars, variable and binary stars; open, diffuse and globular clusters; and galaxies, there’s also the Moon in different phases, so even for observing the Moon, it’s great. And it ends with planets, asteroids and comets, of which only the comets are something that might be interesting to look at with binoculars.

For those wondering, why would there be separate books for observing the sky with binoculars, here are the reasons:

1. The magnification with binoculars is usually somewhere between 7 and 20, while with a telescope you’d usually use a magnification upwards from 30 or so.

2. Good binoculars cost less than a good telescope

3. It makes more sense to start off by observing with binoculars to get to know the brightest objects in the night sky and how to find them, rather than to buy an expensive telescope with which you’ll have difficulty finding anything more interesting than the moon or planets (unless it’s automatic, in which case “Run! The machines are taking over the… sky!!”)

4. It will hurt your face to hold one of your eyes shut for hours. You don’t need to do that when using binoculars or just stra-gazing without any optical instruments.

So to sum up – if you’re bored and it’s daytime and this is the only book you have, you might do well to have a pillow nearby in case you fall asleep. If it’s nighttime and the sky is clear, get a red flashlight, and go outside and try to find Waldo… or Vega or Achernar.
In the night-time it would be really useful, though that might be the time when you actually have a pillow around…

It’s a good book for people just starting to learn about the night-sky, but it’s a little beyond basics.
