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.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eWho It's For\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eKey Features \u0026amp; Design\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMade for the FSQ-106ED:\u003c\/strong\u003e Takahashi lists this coupling for that telescope.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTW — wide mount:\u003c\/strong\u003e presents Takahashi's wide mount thread for camera adapters and T-mounts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMechanical only:\u003c\/strong\u003e no optical elements, so it does not change focal length or field.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eRecommended Uses\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003ePrime-focus astrophotography on the FSQ-106ED, joining the telescope or corrector to a wide-mount camera adapter.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eCompatibility and Accessory Notes\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eListed 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.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eGood to Know Before You Order\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSimilar codes across the range:\u003c\/strong\u003e Takahashi's couplings are distinguished by short suffixes.
