Couplings are the joining pieces of a Takahashi train — each one carries a particular thread pairing and a particular optical length, and the numbered codes are how Takahashi keeps them apart.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eWho It's For\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eThis is a good match if you own a Sky-90 and are assembling or repairing the train that connects it to a camera or visual accessory.\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 Sky-90:\u003c\/strong\u003e Takahashi lists this coupling for that telescope.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e#10 DT form:\u003c\/strong\u003e one specific coupling in Takahashi's numbered range.\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\u003eAssembling a Sky-90 imaging or visual train, joining the telescope to the camera adapter or accessory that follows it.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eCompatibility and Accessory Notes\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eListed for the Sky-90. Takahashi's numbered couplings are close cousins of one another and neither the thread pairing nor the optical length is published on this listing — both matter when a corrector has a backfocus figure to hit. Tell us what you are joining and we will confirm 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\u003eNumbered range, similar parts:\u003c\/strong\u003e Takahashi's couplings differ by number rather than by name.
