The Explore Scientific 72 degree ED 30mm eyepiece with a 2 inch barrel is built for ultra wide, low magnification viewing that allows you to fully immerse yourself in the night sky. It is particularly well suited for observing large nebulae, open clusters, and sweeping star fields. The 2 inch barrel design enhances the field of view, allowing for a broader and more expansive perspective. Combined with the 72 degree apparent field of view, this creates a truly immersive viewing experience.

The extra low dispersion glass maintains image quality across the field by reducing chromatic aberration and improving contrast. This ensures that even at lower magnifications, the view remains sharp and well defined. The eyepiece is designed for comfort, with long eye relief that supports extended observation.

This focal length is ideal for those who want to explore the sky at a wider scale and appreciate the full structure of large celestial objects.

Ava F. ★★★★★

I was blown away by how much of the sky I could see through this 30mm eyepiece—the 72-degree field makes star-hopping effortless. The 2-inch barrel feels solid and secure in my focuser, and the view stays sharp even at the edges.

Thomas S. ★★★★★

The 2-inch barrel fits securely in my focuser, and the 30mm focal length gives such a wide, immersive view of the Milky Way that I don't want to stop looking.

Riley ★★★★★

The 72-degree field of view is a game changer for sweeping starfields—it makes the whole Milky Way feel like it's right there with you. I was honestly surprised how sharp the stars stayed even at the very edge of the image.
