Product Details

Description/Uses:

  • Photo adapter for Takahashi FC-60 refractor with M42 / T / T2 male threads.
  • Features an M56x0.75 female thread on one side and an M42x0.75 male thread on the other side.
  • Recessed 5mm below the M56 female thread is an M52x0.75 female thread, so this might be able to function as an M52x0.75 female to M42x0.75 male thread adapter (please check specifications below for clearance requirements).
  • Also comes with an M42x0.75 female threaded lock/orientation control ring which allows you to vary the spacing or orientation of your imaging camera or other M42/T threaded accessory.

  • Precision machined, black anodized aluminum
