4x40 Telescope (black)

• ‌4 x 40
• Easy to attach

The 4x40 prism telescope is the standard telescope for sextants.

It has a high light intensity for observations at twilight and a lower magnification for a steady image. It also has sufficient magnification for terrestrial horizontal angle measurements.

The telescope can be easily attached and replaced using a clamping screw on the sextant. As a second telescope, it can be safely stowed away in our wooden case with the aid of an optional mounting block.
