Add an intriguing item to your decor with a decorative telescope. Whether you're a novice stargazer or looking to upgrade your view of space, we break down the basics when it comes to buying a telescope. Read more below about telescope types, apertures, and features. You will find the right one for casual stargazing, or expand your telescope collection.

Telescope Usage and User Level
Look for a telescope based on your level of experience and interest; user levels range from kids and beginners to enthusiasts and professionals. The other main point to consider when buying a telescope is what you plan on viewing.
For viewing close stars, the moon, and planets, you need a crisp resolution and aperture (no less than 2 inches).
For viewing galaxies and nebulae, you will need a much larger aperture (5 to 8 inches) and telescope .
For astrophotography purposes, you will need a catadioptric or computerized telescope with medium aperture (4 to 6 inches).
Telescope with an equatorial mount
Decorative: Has no inner telescope technology or very low aperture for mainly decor purposes.
Refracting: Uses a lens to gather and focus light.
Reflecting: Uses a mirror to gather and focus light.
Catadioptric: Combination of refracting and reflecting lenses. Often used in cameras.
Optical Tubes: Usually a refractor lens with expanding tubes for extended vision (also called a double refractor).
Binocular: Dual-aperture telescope for high-quality viewing.
Solar: Special telescope and lens designed for looking directly at the sun.
Dobsonian: Stable yet portable type of telescope base that's ideal for standard stargazing.
Telescope with optical tubes
Aperture levels regulate the brightness and sharpness of your view. The aperture has a range of levels depending on the diameter of the main lens or mirror. Generally speaking for telescopes, the higher the aperture, the higher quality the picture will be. While having a good aperture is crucial to the quality of your field of vision, it doesn't necessarily mean you have to choose the largest telescope possible. For a backyard set-up, consider a larger telescope. For stargazing near a city in a small space, consider a compact but powerful telescope.
Alt-Az Mount (alt-azimuth): A basic two-axis mount for supporting and rotating a piece of equipment vertically and horizontally. Must rotate on both axes separately to follow astronomical objects.
Equatorial Mount: This high-end mount mimics the rotation of the earth when following astronomical objects by rotating on a single axis at a constant rate.
Goto technology: A mount with software that allows the user to track astronomical objects by computer. This also allows manufacturers to offer a simple Alt-Az mount with the ability to easily track objects.
GPS technology: Computerized GPS telescopes simplify the process of finding stars and astronomical objects by mapping the sky for you.
