Design Features
Uniform Flat Field
Precisely corrects field curvature, delivering evenly sharp and round stars from the centre to the edges of the frame.
Bright, Vivid Imaging
Maintains over 95% relative illumination across full-frame sensors, effectively suppressing vignetting and preserving image brightness.
Native Focal Ratio
Preserves the 60GT’s original 360mm focal length and f/6 focal ratio, ensuring optical performance remains fully optimised.
Full-Frame Optimised
Triplet optical construction ensures a flat field and sharp stars from centre to corner when used with full-frame cameras.
