Product Description

Celestron • NexStar 90SLT 90mm Maksutov-Cassegrain Computerized Telescope • 22087

The NexStar 90SLT Maksutov-Cassegrain Computerized Telescope is an excellent beginner scope for planetary observing. Maksutov-Cassegrains use a meniscus lens, causing them to have a very slow focal ratio. The NexStar 90SLT has a focal ratio of f/14 which create smaller field of views than Schmidt-Cassegrains, therefore making them better for looking at planets and objects with very high surface brightness. Even from light polluted areas, the moons and cloud bands of Jupiter, rings of Saturn, and polar ice caps of Mars will all present amazing views. The alignment procedure is also easy as 1, 2, 3! The viewer doesn't need to know the names of any stars, just the date, location, and time. The small camera attached will take three separate images of the night sky and will match them according to its database and from there will align itself. Stargazing can begin!
