The Sky-Watcher Startravel optical tube is an achromatic refractor with 120mm aperture and 600mm focal length. Although it does not have the same performance as an apochromatic telescope, this instrument is functional in various applications where the short focal length is an advantage. For example, it is recommended for those looking for a refractor for deep sky objects at low magnifications, thus obtaining exceptional wide-field views.

The achromatic optics with a 120mm diameter and 600mm focal length with a focal ratio of f/5 will allow you exceptional performance in the rich field, guaranteeing extraordinary observations of clusters, galaxies and nebulae. Ideal for those who wish to travel light and comfortable, this optical tube is also perfect for use in astrophotography as a guide telescope with long focal lengths.

Includes Vixen/EQ5 type rings and dovetail and 31.8mm eyepiece holder with built-in T2 thread.
