A telescope that is a classic achromatic refractor. It has a objective lens with a diameter 90 mm and a focal length 900 mm. The light intensity of the lens is equal to f/10.

It is equipped with a good quality 6x30 finder. Azimuthal AZ3 mount despite its size, it is a lightweight design that allows you to rotate the telescope vertically and horizontally. Thanks to micromotion in both axes, the degree of precision of the observations carried out is higher.

The 1.25" standard gear eyepiece focuser is terminated with a screw mount for an angle cap. It is worth noting that the focuser is compatible with the Sky-Watcher focuser drive. This telescope will allow you to trace all objects in the Messier catalog and a large part of the NGC catalog.

Included with the telescope
6x30 searchlight
1.25" eyepieces - Super 25, Super 10
