Expansive Panoramic Astronomy

Stepping up to an 82° apparent field of view changes how you explore the night sky, removing the restrictive "porthole" sensation common to standard designs. You take in large star clusters and sweeping nebular structures with generous surrounding context, keeping your targets centered longer before needing telescope adjustments.

Dedicated Multi-Element Optics

At the heart of the eyepiece is a sophisticated 7-element optical design engineered for strong contrast and crisp rendition across the field. Each optical surface is treated with broadband anti-reflection film to reduce glare, maximizing visual brightness during critical observations.

Precision Metal Craftsmanship

Engineered with precision CNC machining, the eyepiece body delivers a clean tactile feel and rugged reliability in cold night conditions. Its standard 31.8 mm (1.25") barrel diameter slots seamlessly into any telescope diagonal or focuser built for the format.

Immersive 82° Apparent Field
Experience a vast panoramic perspective that fills your peripheral vision and draws you directly into deep space.
