CAA（カメラアングルアジャスター） FS-78/60C、FC-60E、SKY90II 望遠鏡用 (TKA21200)

Rotating the camera to frame a shot used to mean loosening and re-tightening screws on my FS-78, but this adjuster makes it a smooth twist-and-lock process. The knurled ring turns with just the right amount of resistance, and the whole thing feels rock solid once it's snug.

The locking ring is perfectly knurled, giving a solid grip even with cold fingers out in the field. Rotating the camera to frame M42 was buttery smooth.

Finally, a camera rotator that doesn't fight me—the smooth action on my Sky-90II lets me dial in composition without jarring the focus. Build quality feels exactly right for a precision instrument.
