APM ULTRA FLAT FIELD 18MM EYEPIECE 65° FOV

The 1.25" UltraFlat Field Eyepieces are made to a high quality standard with a very compact design, which is designed to remove the field curvature at the edge, resulting in a flat, distortion-free image within the visible field of view.

The APM Ultra Flat Field eyepiece series is a further development in field correction and viewing comfort. This series offers incredible performance, such as high-quality FMC multi-coating and effective internal blackening of the housing components which produce high-contrast, colour fidelity and a sharp image.

The UFL 18mm 1.25" model is a great all-round eyepiece. This eyepiece is ideally suited for longer focal lengths or for lower overview magnifications. The optical construction has 8 lenses in 5 groups and with a pupil distance of 20mm, it is comfortable for observers who wear glasses.
