Difficulty: Moderately Easy
Things You’ll Need:
Step1
Consider your viewing needs. If you intend to view the heavens from your deck or backyard, portability isn't an issue; but, if you intend to take your telescope to other locations for optimum viewing, then portability can make a big difference. Consider the ease of transporting the telescope, the time it will take to set it up, and the weight of the telescope. Can one person reasonably move and set it up?
Step2
Avoid purchasing a telescope that has been advertised as high powered. In viewing celestial objects the power of magnification isn't what creates a great view. It is the amount of light the scope will take in, or the aperture, that will determine how clearly you will see objects in the night sky.
Step3
Consider a basic refractor telescope with a 60mm to 80mm lens if you are only interested in viewing the moon and planets. These telescopes are easy to transport, require little maintenance, and cost anywhere in the $100 to $300 range.These are not well suited for viewing deep sky objects like galaxies and nebulae, but are great as a starter telescope.
Step4
Contemplate purchasing a reflector telescope, if you wish to observe deep sky images. Those with 6- to 8-inch apertures will capture galaxies and nebulae, but are larger and more difficult to move and come with a price tag beginning in the mid $300.
Step5
Choose a telescope that most closely matches your needs. It may be tempting to buy a high powered telescope that promises high magnification. Keep in mind it is the aperture not the magnification that matters.
