Takahashi TSA-120 Double Tube Holder 125WM

Product Overview

The 125WM is a double-ring tube holder for the Takahashi TSA-120, sized to a 125 mm tube diameter. Two rings carry the tube across a span rather than clamping it at one point. This version closes with head screws rather than the black knobs used on some other Takahashi holders — a lower-profile fastening, tightened with a tool rather than by hand.

Who It's For

This is a good match if you own a TSA-120 and want the two-ring holder, or specifically want the head-screw version rather than the knob version.

Key Features & Design

• 125 mm bore: sized to the TSA-120 tube diameter.
• Double-ring construction: two ring positions rather than one clamp point.
• Head screws, not knobs: a lower-profile closure, tightened with a tool.

Recommended Uses

Mounting a TSA-120 to a Takahashi equatorial mount for visual observing or deep-sky imaging, where a two-ring holder is preferred over a single clamshell.

Compatibility and Accessory Notes

Sized for the 125 mm tube diameter of the TSA-120 — the same diameter as the FSQ-106EDX, which takes its own 125 mm holders. We also stock the 125S clamshell for these tubes. If you want to compare the two before choosing, get in touch and we will talk it through.

Good to Know Before You Order

Head screws rather than knobs: this version is tightened with a tool rather than by hand, which is worth knowing if you swap tubes often in the dark.

Sized to one tube diameter: the 125 mm bore does not adjust to other Takahashi tubes.

Frequently Asked Questions

Is it difficult to set up?

No — the rings open to seat the tube and close around it. The head screws take a tool rather than hand-tightening.

What tube diameter does it fit?

125 mm — the TSA-120.

How does it differ from the 125S clamshell?

The 125S is a single clamshell; this is a two-ring holder. Both fit 125 mm tubes.

Bottom Line

A 125 mm double-ring holder for the TSA-120, closed with head screws rather than knobs.
