Telescopes
If you, like the ancient author, are inclined to "lift your eyes and look to the heavens" you will soon be in the market for a telescope. Telescopes have been around since 1500 AD, but today's technology has increased their effectiveness many times over that of their ancient relatives. With an expenditure of a couple hundred dollars to over a thousand dollars, an amateur astronomer can now view the heavenly population of planets, comets, and all kinds of nebulae.
