Takahashi Coupling TW for FSQ-106ED

Product Overview

A Takahashi TW coupling for the FSQ-106ED. In Takahashi's range, "TW" marks a coupling that presents the wide mount thread — the standard Takahashi camera adapters and T-mounts attach to. It is the joining piece between the telescope side of the train and the camera side.

Who It's For

This is a good match if you are assembling an imaging train on an FSQ-106ED and need the Takahashi coupling that carries the wide mount thread.

Key Features & Design

• Made for the FSQ-106ED: Takahashi lists this coupling for that telescope.
• TW — wide mount: presents Takahashi's wide mount thread for camera adapters and T-mounts.
• Mechanical only: no optical elements, so it does not change focal length or field.

Recommended Uses

Prime-focus astrophotography on the FSQ-106ED, joining the telescope or corrector to a wide-mount camera adapter.

Compatibility and Accessory Notes

Listed for the FSQ-106ED. Takahashi's coupling range uses closely similar codes across telescopes and lengths, and the optical length of each is what decides whether the train still lands on its required backfocus — a figure this listing does not publish. Send us your telescope, corrector and camera and we will confirm both the coupling and the spacing before you order.

Good to Know Before You Order

Similar codes across the range: Takahashi's couplings are distinguished by short suffixes. Confirming the code against your train is worth the message, and we will do it for you.

Optical length is not published: if your corrector has a spacing figure to hit, that total is what matters. We can add it up with you.

Frequently Asked Questions

Is it difficult to set up?

No — it threads into place between the telescope side and the camera adapter.

Which telescope is it for?

The FSQ-106ED.

What does "TW" mean?

It marks the wide mount thread version — the thread Takahashi's camera adapters and T-mounts screw onto.

Does it change the focal length?

No — there are no optics in it.

Bottom Line

Takahashi's TW coupling for the FSQ-106ED, presenting the wide mount thread that the camera adapters attach to.
