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 Scientific’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” eyepiece holder.
The backfocus distance for this flattener is 45mm.
The corrected image circle is 38mm, and will provide 85% illumination to 35mm.
