How to Select a Portable Astronomy Telescope
A telescope is a link to the heavens, and depending on how much of an enthusiast you are, you're going to want to have it with you when you travel. The problem is, some telescopes are simply not portable, making it difficult to transport to new locations for stargazing. Fortunately there are a number of portable telescopes to select from.

Tips & Warnings
Remember to replace the lens cap whenever you're not using your portable telescope. The mirrors and lenses are incredibly sensitive, and sometimes all it takes is a little dust to scratch the surfaces.
Don't use a telescope to look at the sun. The combination of the sun's rays and the telescopes focus will severely damage your eyes and eventually blind you.
