David Astro Universal Field Flattener - 2"

Optimized for refractors with focal ratios of f/5 to f/7, the David Astro 1.0x Field Flattener performs best with APS-C sensor cameras. It’s also compatible with slightly faster or slower refractors when used with smaller 1” and 4/3” sensors, offering flexibility for various imaging setups. The flattener features standard M42x0.75 T/T2 threads for easy connection to the camera and a 38mm clear aperture, perfectly suited for APS-C sensors and smaller.
