M52-M54 Ring

M52 to M54 Adapter Ring for Takahashi Telescopes

This precision-machined adapter ring features M52 x 0.75 female threads on one side and M54 x 0.75 male threads on the other, making it an ideal solution for integrating modern imaging gear with classic Takahashi telescope setups.

Designed Compatibility:
Engineered for use with Takahashi telescopes like the FS-60CB, FC-76D, and FCT-65D, this adapter replaces the Camera Mount DX-60W and provides a direct M54 connection with 55mm back focus—perfect for many cooled CMOS cameras.

Key Applications:

• Seamless connection for cameras with standard M54 threads, including the ZWO ASI2600MC DUO and ZWO ASIAIR

• Use with M54-threaded mounts and accessories like the Askar M54 Camera Adapter ML or ZWO CAA

• Optimal for full-frame cameras such as the ZWO ASI6200MC Pro when paired with an M54 ring to minimize vignetting

Specifications:

• Total Length: 10mm

• Optical Path Length: 6mm

• Thread Types:
  • Telescope Side: M52 x 0.75 (female)
  • Camera Side: M54 x 0.75 (male) + M48 x 0.75 (female)

• Outer Diameter: approx. 61mm

• Inner Diameter: approx. 47mm

• Offset (M52 base to M54 base): 1mm

Why Choose This Adapter?
It provides a cleaner, more direct connection for modern astrophotography setups, improves optical alignment, and helps reduce vignetting—especially with larger sensors.
