This converter increases the magnification obtained from the eyepiece to 1.6x. With an optical design carefully considered for use with the NAV-SW series, it not only achieves a 1.6x increase in magnification, but also provides even better correction of field curvature and astigmatism. Furthermore, it employs a chucking method that minimizes eccentricity. Optical design improves magnification by 1.6x. Corrects field curvature and astigmatism. A chucking method with minimal eccentricity

The Nikon EiC-16 Eyepiece Innovative Converter is a dedicated magnification-boosting accessory designed specifically for use with Nikon's NAV-SW series astronomical telescope eyepieces. It increases magnification by 1.6x, giving observers greater reach for detailed viewing of celestial objects.

Beyond magnification, the converter's optical design also corrects field curvature and astigmatism, helping maintain a sharp, clear image across the field of view rather than sacrificing edge sharpness for higher power. It employs a precision chucking mechanism engineered to minimize decentration, ensuring accurate optical alignment when attached.

With a standard 31.7mm (1.25") barrel size, the EiC-16 attaches easily between the telescope and NAV-SW eyepiece, offering astronomy enthusiasts a simple way to extend their eyepiece's versatility without compromising image quality.
