Takahashi Visual Coupling L (TKP00104)
Manufacturer Part # TKP00104
Takahashi Visual Coupling L (TKP00104)
When an extra 20 mm of optical length is needed between M43 components and 1.25″ accessories, the TKP00104 “Coupling L” comes into play. Otherwise similar in build and finish to the “Coupling S,” this longer barrel allows finer adjustment in complex visual or imaging trains—preserving room for focus adjustment and mechanical balance.
Its sturdy design, precise threads, and tactile grip reveal once more how Takahashi transforms small parts into elegant, functional components of a larger optical legacy.
Cloudy Nights Community Insight:
Observers often point out that this coupling is ideal when using rotators or off-axis guiders, allowing the focus tube to stay near mid-range—where it tracks best during long sessions.
Observing Tip:
Use “Coupling L” instead of “Coupling S” when you find your drawtube nearing its travel limits. It buys extra focus range and balance, especially in heavy visual or imaging rigs.
