PRODUCT DESCRIPTION
- Correct the field curvature of the Esprit 100 with this Sky-Watcher M48 Field Flattener. It offers a clear and wide aperture to ensure minimum halation while increasing the refractor's imaging circle to 40 mm. An effective addition to the triplet refractor, this doublet field flattener uses a precision thread to keep the lens groups aligned to the optical axis and perpendicular to the image.
