Levenhuk Skyline PRO 90 MAK is a catadioptric telescope with a Maksutov-Cassegrain optical design. This design allows for a long focal distance, 1250 millimeters (49.2 inches), to be packed into a tube only 25 centimeters (9.8 inches) long, meaning you can easily go stargazing in the countryside. The 90 millimeter (3.5 inch) aperture and long focal distance make this telescope perfect for high-power planetary observations and deliver high-quality views. At medium power, you can observe various deep-sky objects, such as nebulae and star clusters. This model is for those who do not want to worry about carrying bulky equipment into the countryside for observations, but still want to have a powerful tool for their observations. Furthermore, this telescope can be easily mounted on a standard tripod and, with the addition of an erect prism, it can become a powerful spotting scope for terrestrial observations.
