TMB Planetary Eyepiece – 5mm (58°)
The TMB Planetary 5mm eyepiece is designed for high-power visual observing, delivering excellent contrast and sharpness for lunar and planetary observation. With a comfortable 58° apparent field of view, it provides an immersive experience without the tunnel vision often associated with traditional high-magnification eyepieces.

This eyepiece is well suited to observing fine details on the Moon, Jupiter, Saturn, and Mars, while maintaining comfortable eye relief and easy eye positioning. The optical design helps minimise aberrations and maximise contrast, making it a popular choice for serious visual observers.
Finished in matte black with a robust mechanical design, the TMB Planetary eyepiece is compatible with a wide range of telescopes and is ideal for both beginners and experienced astronomers looking to expand their high-power eyepiece collection.
