TS Optics Flattener 1.0x M63 (69834)

The TS Optics Flattener 1.0x M63 is designed to correct the field curvature that naturally occurs with primary telescope optics, ensuring that stars remain sharp and focused all the way to the edge of your astrophotography images. This accessory is particularly suitable for apochromatic telescopes with apertures greater than 500mm, and it is installed between the telescope and the camera. The flattener features fully multi-coated optics for optimal light transmission and includes a filter thread for added versatility. Its robust aluminum construction and flexible backfocus options make it a reliable choice for demanding astrophotography setups.

This flattener is an excellent solution for astrophotographers seeking sharp, distortion-free images across the entire field when using large-aperture apochromatic telescopes.
