Takahashi Multi-Adapt Coupling TW for FSQ-106 / FSQ-106ED (M92 to M72)

Product Overview

A Takahashi reduction adapter for the FSQ-106 and FSQ-106ED, converting between M92×1 and M72×1. The M92 side is the telescope-mounted external thread; the M72 side takes the smaller components that follow it in the train.

Reduction adapters like this are what let a large-diameter telescope interface meet the narrower threads that camera adapters and correctors use, without an improvised stack in between.

Who It's For

This is a good match if you are assembling an imaging train on an FSQ-106 or FSQ-106ED and need to get from the telescope's M92 thread down to M72.

Key Features & Design

• M92×1 to M72×1: the two threads this adapter joins.
• Telescope-mounted external M92 thread: the side that meets the FSQ-106 or FSQ-106ED.
• Mechanical only: no optical elements, so it does not change focal length, focal ratio or field.

Recommended Uses

Assembling an FSQ-106 or FSQ-106ED imaging train where the components downstream of the telescope use the M72 thread.

Compatibility and Accessory Notes

Listed for the FSQ-106 and FSQ-106ED. Takahashi does not publish this adapter's optical length, and that is what decides whether your train still lands on its required backfocus once everything is threaded together. Send us your corrector, spacers and camera and we will add the total up with you before you order.

Good to Know Before You Order

Optical length is not published: every adapter contributes to the backfocus total, and if your corrector has a spacing figure to hit, that total is the number that matters. We are glad to work it out for you.

Mechanical only: this adapter changes the thread and nothing else.

Vendor code inconsistency: Takahashi's own listing text refers to code TKP36001 while the part is catalogued and supplied as TKP30003. We list it under the supplied code; ask us if you want that confirmed against your existing parts.

Frequently Asked Questions

Is it difficult to set up?

No — it threads on between the two components. The thinking happens beforehand, in the backfocus total.

What threads does it convert?

M92×1 on the telescope side to M72×1 on the other.

Which telescopes is it for?

The FSQ-106 and FSQ-106ED.

Does it change my focal length?

No — there are no optics in it.

Bottom Line

An M92×1 to M72×1 reduction adapter for the FSQ-106 and FSQ-106ED — the piece that gets the telescope's thread down to the size the rest of the train uses.
