The absolute WORST thing you can do to a bright child who shows a burning interest in the stars and astronomy is to buy them a toy telescope!! If Leonardo da Vince, Hubble or any of the pillars of astronomy were turned off by a toy telescope during their youth, we would probably know a lot less about the cosmos today.
What's wrong with a toy telescope? For openers the lenses are cheap (often made of plastic). Cheap lenses produce lousy, blurred images with plenty of uncorrected color. Most of the telescope parts are made of plastic, rather than metal. The tripod (a very important part of the telescope) is poorly made and is almost 100% plastic. It all adds up to a terrible experience for the child...something you would hope to avoid.
So, if you can't afford spending about $300 minimum for a basic usable telescope, buy the child a good astronomy book. Believe me, the child will get a lot more out of the book and will not be turned off.
