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.
