It threads on with an M55.9 x 0.75 fitting and Takahashi publishes two length figures for it: 12.3 mm, measured from the tip of the left ring to the base of the male thread, and 20 mm, the part's outer thickness. It's the current version of what Takahashi previously sold as the CAA (Sky-90), and the two are interchangeable.\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 through an FS-78, FS-60C, FC-60E, or Sky-90 II and want to rotate your camera to frame a target without breaking down the imaging train to do it.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eKey Features \u0026amp; Design\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eM55.9 x 0.75 threaded fitting:\u003c\/strong\u003e matches the drawtube interface on the FS-78, FS-60C, FC-60E and Sky-90 II.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull rotation, then lock:\u003c\/strong\u003e turn the camera to the framing you want and lock it for the exposure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo published length figures:\u003c\/strong\u003e Takahashi lists both a 12.3 mm reference measurement and a 20 mm outer-thickness figure for this part — real numbers to build into your backfocus total.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible with the earlier CAA (Sky-90):\u003c\/strong\u003e a direct match if you're adding to or replacing a part in an existing Takahashi imaging train.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eRecommended Uses\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eFraming adjustments on FS-78, FS-60C, FC-60E and Sky-90 II refractors; rotating a guide or imaging camera to align a target without loosening the whole train; quick reframing between targets in an observatory setting.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eCompatibility and Accessory Notes\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eThreads with M55.9 x 0.75 into the FS-78, FS-60C, FC-60E and Sky-90 II drawtube.
