TS Optics 360° Rotating Adapter - M68x1 Male and Female Threads
Any astrophotographer working with a professional M68x1 ZEISS-style thread system knows how important it is to rotate the camera precisely - without taking the entire optical train apart. This TS Optics M68x1 rotating adapter solves that problem directly: it is compact, elegant, and adds minimal length to your imaging setup. One side carries a female M68x1 thread. The other side offers both a male M63x1 and a male M68x1 thread. This means you can connect your focuser to a camera or other accessories without needing extra reducers in between.
Smooth 360° rotation with a single locking screw
Rotation is smooth across the full 360° range. Once you have the angle you want, a single large knurled screw locks the position. No tools needed - one firm turn of your thumb and the camera stays exactly where you placed it. You can also fine-tune the rotational resistance using five set screws, so the adapter works equally well with a lightweight mirrorless camera and a heavier camera body with accessories attached. The inner ring self-centres during tightening, keeping the optical axis precisely aligned.
Built for heavy accessories
The adapter is designed with thick walls and generously long threads. This matters when you attach heavier accessories such as round filters, filter wheels, or large medium-format cameras. Lightweight adapters in these configurations can flex or develop thread play, which shows up in your images as motion blur or asymmetric star shapes. That does not happen here - the robust construction of the TSM6863Rot handles demanding accessory combinations without any compromise in joint rigidity.
No vignetting, minimal back focus impact
The 59 mm clear aperture means the adapter itself will not introduce vignetting, even with fast optical systems covering a large image circle. The total optical length is just 21.8 mm, measured without the male M68x1 thread. You can fit this adapter into an existing back focus calculation without significant changes to your setup.
Wide compatibility with professional imaging systems
This adapter fits any focuser or accessory with a female or male M68x1 or M63x1 thread, which covers most professional astrophotography systems. No additional reducers are required. Compact dimensions, precise machining, and a well-thought-out locking mechanism make this a reliable foundation for night imaging at any rotation angle.
