The large GT153 triplet apochromat for full-frame cameras: FPL-53 glass for high colour correction, crisp images and, thanks to the relatively large aperture, excellent resolution – a dream for astrophotographers! To achieve this performance, each lens is tested with a Zygo interferometer and then mounted in the precision CNC-milled lens mount. Faulty lens mounts often undermine the potential performance of the lenses in cheap refractors. It is worth investing in the excellent finish from William Optics!
The 3.5" Feather Touch focuser meets the high demands of discerning astrophotographers: smooth focusing, no slipping or image shift, 360° rotatable and, of course, counterbalanced.
The scope includes a Bahtinov mask specially developed by William Optics for optimal focusing. Also included is the 3" Rotolock, which allows any accessories to be clamped securely and centred.
