Explore Scientific 68° Ar Eyepieces

These eyepieces are ideal all-rounders. They can be used for lunar and planetary observation as well as for observing nebulae, star clusters and galaxies. The generous field of view of 68° provides a distinctive wide-angle effect. Nevertheless, the edge of the field of view is visible. Thus, even an inexperienced observer automatically has the right view.

The barrel is tapered at the upper end. This always guarantees a secure fit. The advantage to a locking groove is that this eyepiece cannot get caught with ring clamps. Nevertheless, tilting is impossible.

Durable and robust due to argon filling

These eyepieces not only stand for optical performance, but also for durability. You can clean the eyepiece and the outer lens surfaces with the appropriate cleaning fluid without any problems. It will not penetrate the eyepiece interior, nor will dew or dust. The eyepiece interior will be like new even after years. The eyepieces are waterproof.
