TS-Optics GPU Superflat 2" 1x Newtonian Coma Corrector (SKU: TSGPU) is a high-performance optical corrector designed for astrophotography with fast Newtonian telescopes. The four-element optical design based on the original GPU-Optics concept effectively eliminates coma produced by parabolic primary mirrors, producing sharp, round stars across the entire image field. The corrector does not change the telescope focal length (1x), preserving the native image scale.

Key features

• four-element Superflat coma corrector for Newtonian telescopes
• excellent coma correction across the entire image field
• no change of telescope focal length (1x magnification)
• suitable for telescopes with focal ratios from f/3.5 to f/6 (optimal around f/4)
• compatible with full-frame cameras depending on telescope configuration
• stars remain small and round without halo effects
• optical design minimizes reflections and ghosting
• tolerant to small tilt errors in the imaging train
• can be installed in a 2" focuser or screwed via M48 thread

Box contents

• TS-Optics GPU Superflat 2" coma corrector
• M48 locking ring
