Technically speaking, for those who want to be researcher and do discoveries with their ideas. Awesome book for bigners , above average book for middle knowledge students . Techinically speaking there are around/more than 600 pages in the book .Bigners can start their carrier with this book(probably) .You will come to know many things. I recomend this book for class 10,11 and above , although i am in class 9. Its really good.( i know grametical errors)
It is definitely a beginner's guide but not a child's guide. If you are enthusiastic about astronomy, you'll not regret your purchase. If you expect large easy to read font and simple illustrations, you may have to rewire your expectations. The font is small, like in college text books.
