National Geographic Telescopes

Telescopes are mainly divided into three types: refractor, reflector, and compound. Refractor telescopes use lenses, reflector telescopes use mirrors, and compound telescopes combine both. Each type has unique advantages, like portability or image clarity, which can suit different viewing needs.

Choosing a telescope depends on your interest and budget. Telescopes with an aperture of 70 mm to 100 mm are ideal for beginners. Look for easy setup and user-friendly features. Consider what you want to observe—planets or deep-sky objects—as this will guide your choice.

Aperture is crucial because it determines how much light a telescope can gather. Larger apertures allow you to see fainter objects and more detail. For clear images of distant stars and galaxies, consider telescopes with larger apertures.

Telescopes are useful during the day for terrestrial viewing with appropriate filters. They can be used to observe landscapes or wildlife from afar. Ensure you never point them directly at the sun without a proper solar filter to avoid damage.

Accessories enhance your viewing experience. Essential ones include eyepieces of various magnifications, a sturdy tripod, and a star map or app for navigation. Optional accessories like filters can improve image quality under specific conditions.
