Baader adapter M54i to T-2a

Description

The Baader adapter M54i to T-2a is a precision reducing ring designed to convert a telescope’s M54 male thread into a T-2 male thread (M42 x 0.75). It allows T-2 female accessories to be easily connected to M54-based equipment.

With an optical path length of only 4 mm and a clear aperture of 39 mm, this adapter integrates seamlessly into optical trains without restricting the field. Compact and lightweight (0.01 kg), it is manufactured from hardened stainless steel, ensuring durability and long-term stability.

As part of Baader’s M54 and T-2 system families, it guarantees broad compatibility with a wide range of astronomical accessories, cameras, and filters. Availability expected mid-April 2025.
