This corrector provides a +4mm adjustment range, ensuring perfect sensor-to-corrector spacing for a variety of cameras and filter setups.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e35mm Back Focus Design for the Takahashi TAK72\u003c\/h3\u003e\n\u003cp\u003eThis corrector transforms the TAK72 into a capable astrograph by eliminating field curvature and other aberrations, ensuring sharp stars across the entire frame.

While this is not noticeable during visual observation, a camera sensor is perfectly flat and will record elongated or out-of-focus stars at the edges and corners of an image. An AG Wynne corrector flattens this field, ensuring that stars are sharp and round across the entire sensor.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWill this AG Wynne corrector work on my 8\" f\/4 Orion Optics UK Newtonian?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eNo. This corrector is designed for the optical system of the Takahashi TAK72 refractor.
