The Explore Scientific 72 degree ED 25mm eyepiece with a 2 inch barrel is designed for expansive, low power viewing that reveals the broader structure of the night sky. It is ideal for observing large deep sky objects and sweeping rich star fields. The wider 2 inch format allows for a larger field stop, enhancing the 72 degree apparent field of view and creating a more immersive experience. This makes it easier to frame large objects and enjoy them in full context.

Extra low dispersion glass ensures that image quality remains sharp and well corrected across the field. Color fringing is minimized, and contrast is enhanced, resulting in a cleaner and more natural view. The generous eye relief allows for comfortable viewing, even during extended sessions.

This eyepiece is a strong choice for those who want to maximize field of view and brightness while maintaining excellent image quality.

Eva P. ★★★★★

The 72-degree field of view really opens up the Milky Way in my 12-inch scope, making star clusters feel almost 3D. I’ve been using it for wide-field sweeping, and the 25mm focal length gives nice, sharp stars across most of the frame.

Emma B. ★★★★★

My 10-inch Dobsonian suddenly feels like a much bigger scope with this eyepiece—the 72-degree field lets me fit the entire Pleiades cluster in one view. Even my light-polluted backyard can't hide the crisp stars across that wide expanse.

Ellie N. ★★★★★

I was blown away by how much more of the Milky Way I could see through this 25mm eyepiece compared to my old one—the 72 degree field really opens up the view. The 2 inch barrel fits solidly in my focuser, and the image stays sharp edge to edge.
