Wide, Bright Views for Deep-Sky Observing

The 40mm focal length produces a bright exit pupil and a wide true field of view, making this eyepiece particularly useful for locating objects and observing large targets such as open clusters, nebulae, and sweeping Milky Way star fields.

Multi-Coated Optics & Image Clarity

Multi-layer lens coatings reduce internal reflections and light loss, resulting in brighter images and improved contrast. This helps reveal faint details in deep-sky objects, especially when observing from darker locations.
