It turns to put the framing where you want it, then locks so the angle holds through a run of exposures.\u003c\/p\u003e\u003cp\u003eThere are no optics inside it. It is a rotating mechanical coupling, and it takes Takahashi wide-mount T-rings on 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 image with an FS-78, FS-60C, FC-60E or Sky 90 II and want to set composition at the telescope. Rotating the camera at the focuser is quicker than unclamping the tube in its rings and rebalancing, and it lets you repeat a framing between sessions instead of guessing at it.\u003c\/p\u003e\u003cp\u003eIt suits anyone shooting elongated targets — edge-on galaxies, long nebulae, comet tails — where the angle of a rectangular sensor decides how much of the object lands on the chip.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eKey Features \u0026amp; Design\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotates and locks:\u003c\/strong\u003e set the camera angle, lock it, and the framing stays put for the sequence.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMechanical only:\u003c\/strong\u003e no optical elements, so it does not change focal length, focal ratio or correction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide-mount T-ring interface:\u003c\/strong\u003e accepts Takahashi wide-mount T-rings on the camera side.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMatched to a specific set of tubes:\u003c\/strong\u003e built for the FS-78, FS-60C, FC-60E and Sky 90 II drawtube rather than as a universal fitting.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTakahashi system part:\u003c\/strong\u003e appears on Takahashi's own FS-60CB system chart as CAA (SKY90), reference TKA21200.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eRecommended Uses\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eFraming deep-sky targets on a DSLR, mirrorless or dedicated astronomy camera.
