With a focal length of 1250mm and a focal ratio of f/13.9, it is the ideal instrument for beginners in planetary astronomy or as a portable second scope for high-magnification observation of planets, the Moon, and double stars.
The Maksutov-Cassegrain design is renowned for its excellent balance between size and optical performance. Despite weighing just 1.3 kg, the Skymax 90 delivers sharp, high-contrast images of Solar System planets. The small secondary mirror obstruction combined with the aluminized mirrors and anti-reflection coating maximise light transmission and image contrast, revealing details that refractors of equal aperture often miss.
Thanks to its weight of 1.3 kg and compact size, the Skymax 90 is ideal both as a beginner telescope and as a travel scope for experienced amateur astronomers. The standard photographic tripod adapter makes it easy to use with any common tripod, while the complete accessory kit — including two Super eyepieces and a 90° mirror diagonal — means you can start observing immediately with no additional purchases. The Starpointer finder simplifies aiming even for first-time observers.
With a maximum magnification of 180x and a 31.8mm (1.25") focuser, the Skymax 90 pairs with any planetary camera for Moon and planetary imaging. The 1250mm focal length provides an excellent image scale even without a Barlow, making it one of the best entry-level telescopes for lunar photography in its price range.
