Baader Adapter M63a to M68i – for Feathertouch 2.5" OAZ / TS-Optics

Description
The Baader M63a to M68i adapter is designed to provide a solid and perfectly aligned mechanical link between accessories using the M68 (Zeiss) thread standard and Starlight Instruments Feathertouch 2.5" or TS-Optics (Photo Line) focusers featuring an M63 x 1 female thread.

It converts an M68 x 1 male thread into an M63 x 1 male thread, enabling seamless integration of M68 optical components into M63-equipped telescopes, without mechanical play or tilt. With an optical height of only 7.3 mm and a clear aperture of 58 mm, it minimises vignetting and light loss while maintaining mechanical rigidity.

Machined from high-quality aluminium, it features a matte black internal finish to suppress stray light and maintain maximum image contrast. This adapter is also part of Baader’s M63a x 1 ClickLock clamp (#2956263), ensuring complete compatibility and optimal integration in professional astrophotography or high-end visual observation setups.

Thanks to its compact design and robust build, it is ideal for demanding configurations where mechanical stability, alignment precision, and multi-system compatibility are essential.
