2" Field Flattener - FFEDAPO-NI
A curved focal plane is an inherent feature in most telescope designs and is nothing to note for general stargazers. But, for astrophotographers, the consequences of that same curved plane can ruin hours of patient imaging. Designed for refracting telescopes, Explore Scientificâ„¢s Field Flattener can tackle the edge-of-field aberrations caused by this necessary curvature to ensure your long night at the eyepiece will not be in vain.
This accessory offers fully multi-coated optics and slides securely into the 2-inch eyepiece holder. This flattener, which has 45 mm of back focus, includes an ULTRA-THIN Nikon T-mount for Nikon Cameras.
