APM Eyepiece XWA HDC 13mm 100° 2"/1.25"

Extreme wide-angle eyepiece designed for the best possible correction of field geometry and color discrepancies.

The robust eyepiece body features a high-quality anodized finish, with a lens system that is fully multi-coated to enhance light transmission and blackened lens edges to reduce glare.

Special Features Include:

• Adaptable from 2” to 1.25” with a removable threaded sleeve (20mm eyepiece excluded).
• Waterproof design.
• Filter threads compatible with both 1.25” and 2” sizes (20mm eyepiece excluded).
• Conical upper end to facilitate use with binocular attachments.
• Detachable eyecups with an M44.5 x 0.75 external thread for camera attachment.
