Two rings carry the tube across a span rather than clamping it at a single point — the arrangement Takahashi uses for the Epsilon astrographs, whose short, wide tubes carry a camera at the prime focus.\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 an Epsilon E-130D and need Takahashi's own holder to carry it on a Takahashi mount.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eKey Features \u0026amp; Design\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e166 mm bore:\u003c\/strong\u003e sized to the Epsilon E-130D tube diameter.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDouble-ring construction:\u003c\/strong\u003e two ring positions rather than one clamp point.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMatched to the Epsilon series:\u003c\/strong\u003e Takahashi builds a separate holder for each Epsilon tube diameter.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eRecommended Uses\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eMounting the Epsilon E-130D to a Takahashi equatorial mount for fast wide-field deep-sky imaging.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eCompatibility and Accessory Notes\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eSized for the 166 mm tube diameter of the E-130D.
