Tecnosky 0.95x Coma Corrector for Newtonians f/4–f/6

Tecnosky 0.95x Coma Corrector for Newtonians f/4–f/6

Description:
The Tecnosky 0.95x coma corrector is designed to enhance edge-of-field image quality in Newtonian reflectors by reducing coma aberrations and slightly shortening the telescope's effective focal length.

Optimized for Newtonians with f/4 to f/6 focal ratios, this corrector is especially suitable for APS-C sensors and can work with some larger sensors depending on configuration. It uses a standard M48x0.75 mm thread and preserves the common 55 mm backfocus, making it compatible with most astrophotography setups including cameras, filter wheels, and off-axis guiders.

Its optical design ensures minimal distortion, high contrast, and excellent correction over a wide field — an ideal tool for wide-field deep sky imaging with fast Newtonian reflectors.
