Designed as a highly portable and user-friendly entry- to a mid-level astronomical observation platform, the Celestron NexStar 90SLT 90mm f\/14 Maksutov-Cassegrain GoTo Telescope gives you the ability to make detailed observations of the Moon, with the ability to easily see planets and reach outside the solar system to resolve bright deep-space objects like galaxies, nebulae, and binary or variables stars.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e The compact and powerful Maksutov-Cassegrain design uses a front corrector plate with a convex meniscus lens to correct off-axis aberrations, like comas, and chromatic aberration to produce images with true color rendition.
