TS Optics Tilter and Adapter - M68/M54
Every astrophotographer knows the problem: stars in the centre of the frame are sharp, but towards the corners they blur or distort. You try to find a compromise focus position that never quite works, or you crop the corners away. These are the usual workarounds - and none of them actually solves the problem.
The cause is often a very slight tilt between the camera sensor and the focal plane. It can come from the camera itself, from the focuser, from the geometry of the telescope's focal plane (particularly common with Newton reflectors), or from the way accessories are clamped on the focuser side. Even a fraction of a millimetre is enough to produce visible aberrations across the image.
What the TS Optics Tilter does
The TS Optics Tilter M68/M54 lets you correct this tilt precisely and repeatably. You adjust the sensor position relative to the focal plane using Allen screws. The adjustment is fine, stable, and stays locked once set. After you find the correct position, you simply keep all adapters, correctors, and the camera in the same orientation - and the correction remains effective.
The result is even sharpness across the entire frame. That is something you cannot achieve by adjusting focus alone.
Design and compatibility
The Tilter is a compact spacer with a height of just 9 mm, so it adds very little to the optical path. The M68/M54 version connects the telescope side (M68 female thread) to the camera side (M54 male thread). The distance from the male thread to the adjustment screws is 11 mm, which gives you enough room to work comfortably during setup.
The standardised M68 and M54 threads make this adapter compatible with a wide range of astrophotography equipment.

Why sensor tilt correction matters
Correcting camera sensor tilt is one of the most overlooked steps in astrophotography - and one of the steps that makes the biggest difference to image quality. The TS Optics Tilter offers a clean and technically sound solution. You do not need to modify the telescope's optics or mechanics in any way.
If you have been struggling with soft corners despite careful focusing, this adapter is worth trying before looking for a more complex cause.
Who is this adapter for
- Astrophotographers who use a camera with an M54 thread on a telescope or corrector with an M68 thread
- Anyone experiencing uneven sharpness across the frame - especially blurry or distorted corners
- Users of Newton reflectors, where focal plane geometry is a common source of tilt
- Photographers who want a precise, repeatable tilt correction without modifying their telescope
Practical notes
Once you set the correct tilt position, keep the relative orientation of all components - the adapter, any correctors, and the camera - the same every time you assemble the setup. This ensures the correction remains accurate from session to session.
The 9 mm height of the Tilter means it fits into most imaging trains without requiring changes to your back-focus distance calculations.
