TS Optics Flattener 1.0x 350mm Apo (69829)

The TS Optics Flattener 1.0x 350mm Apo is designed for astrophotographers who want sharp, flat-field images with apochromatic telescopes of less than 350mm focal length. By correcting the natural field curvature produced by the main optics, this flattener ensures that stars remain sharp and focused across the entire image, from center to edge. The flattener is installed between the telescope and the camera, making it easy to achieve professional-quality exposures. It is especially useful for wide-field imaging and is compatible with telescopes that have an M54 connection.

This flattener is an essential accessory for astrophotographers seeking distortion-free, sharp images across the entire field when using short focal length apochromatic telescopes.
