Explore Scientific 3" Field Flattener and 7" Focal Reducer with 2" Adapter

Explore Scientific's 3" Field Flattener .7x Focal Reducer is a multi-faceted accessory designed to enhance your astrophotography experiences. As a field flattener, this piece addresses the edge-of-field aberrations caused by curved focal planes to ensure your night at the eyepiece will result in crisp, true images. As a focal reducer, this device will reduce your f-ratio by .7, which results in a wider field of view, brighter images and less exposure time. Recommended for Explore Scientific's 127mm and 152mm refracting telescopes, this field flattener/focal reducer boasts fully multi-coated optics and comes with 2 adapters to accommodate different focuser sizes.
