ExtraFlat™ Wide-Angle Eyepieces (1.25")
Edge-to-edge distortion free images
The exotic 1.25” ExtraFlat™ 5 or 6-element eyepiece design packs premium features and high-end performance into a surprisingly affordable package. The optical designer has succeeded to remove peripheral field curvature so now you can enjoy flat, virtually distortion-free images from the centre-to-edge of the field. Optical performance is impressive, with excellent sharpness, contrast and colour rendition. All models feature oversized eye-lens elements, wide fields of view, long eye-relief for spectacle wearers, and soft twist-up rubber eyecups for comfortable viewing. All models are fully broadband multi-coated, feature blackened lens edges and are parfocal. Beautifully finished in high-gloss anodized aluminium with knurled rubber grips. Threaded to accept standard 1.25” filters.
Available in focal lengths of 16mm, 19mm, and 27mm, with apparent fields of view of 60°, 65°, and 53° and eye relief of 17mm, 19mm, and 23mm respectively.Delivery contents
