TS Optics 360° M90 Camera Rotator
In astrophotography, your camera sensor rarely ends up at exactly the angle you need. Framing a target correctly, aligning the sensor with the plane of a galaxy, or simply rotating the field of view to suit your composition - all of this normally means taking your optical train apart and starting again. The TS Optics 360° M90 rotator solves this problem directly: it lets you rotate your camera a full 360° in the plane perpendicular to the optical axis, without affecting the mechanical or optical integrity of your setup.
How it connects
The rotator connects to your telescope or focal reducer via an internal M90x1 thread. On the camera side, it offers an external M90x1 thread. The optical length is 14 mm - a value you need to include when calculating the back focus distance for your complete optical train. The standardised M90 thread makes this rotator compatible with a wide range of cameras and accessories that use this connection size.
Why it saves you time
Instead of removing your camera and rebuilding the entire optical path, you simply release the locking ring, rotate the sensor to the position you want, and lock it again. The result is a precisely framed image - no compromises, no unnecessary adjustments to your setup.
A practical tool for any astrophotographer who wants to spend less time on setup and more time imaging.

Who is this rotator for?
The TS Optics 360° M90 rotator suits anyone who uses a camera with an M90x1 connection for astrophotography. Whether you are imaging wide fields, galaxies, or nebulae, precise sensor orientation without dismantling your setup makes a real difference to your workflow.
Typical uses
- Rotating the field of view to frame a target without moving the telescope
- Aligning the sensor with the plane of a galaxy or other extended object
- Adjusting composition between imaging sessions without rebuilding the optical train
- Use with camera lenses, telescopes, or focal reducers with M90x1 thread
