Sky-Watcher

Sky-Watcher Skymax 90

A compact 90mm Maksutov-Cassegrain that delivers crisp, high-contrast planetary views in a near-zero-maintenance package. The long focal ratio (f/13.9) means any eyepiece in your collection will perform well, and the sealed tube design means you will never need to collimate it. The trade-off is the narrow field of view — this scope finds planets and the Moon rather than sweeping through star fields. A popular grab-and-go choice for observers who want sharp planetary views without carrying a large telescope.
