National Geographic 114/500 Compact Telescope With its 144-mm aperture, this telescope collects three times more light than a 76-mm telescope. Therefore, fainter objects become visible, and you can see more details of the moon and planets. Nevertheless, the telescope is very compact and sets up quickly, with no assembly required, so it can be transported to your favourite night-sky-observation location easily. Use is very intuitive, without compromising stability. The built-in accessory tray keeps the eyepieces handy, and the red-dot finder makes locating objects simple.
