Flatten the field and speed up your focal ratio in one step. The Explore Scientific 3-inch Field Flattener & 0.7× Focal Reducer (FFFR507X-00) corrects the field curvature common in many refractors — delivering sharp, round stars edge-to-edge across a full-frame imaging sensor — while simultaneously reducing your focal length by 0.7× for faster imaging and a wider field of view. Essential for deep-sky astrophotographers who want to cover large targets like nebulae and galaxy clusters without sacrificing star shape at the corners. Uses M48 thread. Ships free to the US.
