Explore Scientific Field Flattener f/5 to f/7The Explore Scientific Field Flattener corrects field curvature for sharp, round stars across your entire imaging sensor. Refractor telescopes produce a curved focal plane, but camera sensors are flat without a field flattener, stars at the edges of your frame appear elongated or distorted. This fully multi coated flattener with 38mm clear aperture corrects that curvature without changing your telescope's focal length or f ratio. The 2" barrel and
The Explore Scientific Field Flattener corrects field curvature for sharp, round stars across your entire imaging sensor. Refractor telescopes produce a curved focal plane, but camera sensors are flat — without a field flattener, stars at the edges of your frame appear elongated or distorted. This fully multi-coated flattener with 38mm clear aperture corrects that curvature without changing your telescope's focal length or f/ratio.
The 2" barrel and M42x0.75 T-thread interface connect directly to your camera via a standard T-ring (sold separately). Back-focus distance is 55mm, matching the Explore Scientific corrector/reducer ecosystem for consistent spacing.
Note: This is an astrophotography accessory — it is not intended for visual use.
