Excellent beginners telescope

The National Geographic 70/900 is an excellent beginners telescope. This refractor or lens telescope can be used for astronomical observations as well as nature observations.

User friendly

The MPM mount can best be used in azimuthal mode when doing land observations. For astronomical observations you can use the equatorial mode. This allows you to effortlessly and smoothly follow a celestial object. Despite its versatility, this mount is incredibly flexible, compact and light. Working with this telescope is therefore also very easy for beginning users.
