The telescope offers magnification options ranging from 23x to 200x, making it suitable for observing faint deep-sky objects like nebulae, as well as planetary and lunar details. Made from durable aluminum with a white finish, the telescope tube measures 600 mm in length and 103 mm in diameter, weighing 3.9 kg including accessories. The optical system incorporates a 2.5-inch Hexafoc focusing mechanism for precise image adjustment.

Additional features include a 6x30 finderscope for locating objects and the astronomy software Stellarium with a rotating star chart for sky navigation. The light-sensitive design of the telescope allows for the observation of structures in distant celestial objects while maintaining optical clarity and precision. This is a pure optical assembly without a tripod or mount.
