It sits in the optical train between the drawtube and your next fitting, giving you a defined point to build out an imaging or visual chain on this telescope.\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 TOA-130NS or TOA-130NFB and are assembling or extending the camera-side adapter chain for either imaging or eyepiece use.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eKey Features \u0026amp; Design\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt for the TOA-130 family:\u003c\/strong\u003e machined to Takahashi's TOA-130 camera-side interface rather than a universal fitting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact single-purpose ring:\u003c\/strong\u003e adds one connection point to the train without introducing unnecessary length.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAluminum construction with black finish:\u003c\/strong\u003e matches the rest of the TOA-130 accessory line.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eRecommended Uses\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eCamera-train assembly and accessory mounting on the TOA-130 refractor, for both imaging setups and visual accessory chains.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eCompatibility and Accessory Notes\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eFits the TOA-130 optical tube family (TOA-130NS, TOA-130NFB).
