Explore Scientific 2" Field Flattener - FFEDAPO-01

Choose the Explore Scientific 2-Inches Field Flattener for exceptional performance with APS-C and smaller cropped sensors, ensuring a flat field for optimal imaging.

Compatible with Explore Scientific's Achromatic Doublet Series (DAR), Essential Series, and FCD100 Series telescopes (80mm, 102mm, and 127mm diameters).

Threaded design accommodates a 2-inch filter.

Most telescopes have a curved focal plane, inconspicuous for stargazers but a challenge for astrophotographers.

Explore Scientific's Field Flattener, designed for refracting telescopes, addresses edge-of-field aberrations caused by this curvature.

With 55mm back focus (+/- 2mm), fully multi-coated optics, and secure 2-inch eyepiece holder compatibility, this accessory ensures your astrophotography endeavors are fruitful, salvaging hours of patient imaging.
