2,5/5. Not really what I was expecting or searching for! Weird editing choice, a lot of information seem to be on the side of the main subject. Of course street light is important when stargazing in cities, but I can,t do shit about it, so dont explain me how they work or why city choose this type of light or this kind, and just focus on how to overcome or deal with them! If you are looking for some sort of beginners guide, dont go with this one, because even if you will learn a couple of things, overall I think it will left you on your appetite, it sure left me on it! I will review some more book on the subject in the future week, I order a couple of them (trying to get into astronomy with my new telescope!), so maybe we will be luckier next time!
