If you crave sharp, highly detailed views of bright sky objects, such as the Moon, planets, double stars, and sparkling star clusters, then a refractor is ideal. They come in apertures ranging from 2 to 6 inches (5 to 15 centimeters). Smaller models are perfect for anyone who prefers extreme portability — think scopes you might bring on a family camping adventure — or is looking for a quick grab-and-go instrument to run outside with on a given clear night.
