TS Optics T2 Tilter - M42x0.75 - Tilting Compensator

TS Optics T2 Tilter M42x0.75 - tilt compensator

Many astrophotographers know the frustrating moment: stars in the centre of the image are pin-sharp, but towards the corners they blur into ellipses or teardrops. The cause is not always poor focus or a faulty optical element. A slight sensor tilt of just a fraction of a millimetre, a marginally tilted focuser, or a focal plane that is not perfectly perpendicular to the optical axis - all of these are enough to ruin a frame. The problem is especially common with Newton telescopes. Sometimes the culprit is simply imprecise clamping of an accessory somewhere along the optical train. The result is always a compromise: either you hunt for a focus position where most of the field looks acceptable, or you crop the corners away.

The TS Optics T2 Tilter tilt compensator lets you physically align the camera sensor with the focal plane of your telescope - regardless of where exactly the tilt originates. You place the device in the optical train and use the knurled screws to gently adjust the tilt until stars are pinpoints across the entire frame. The knurled screws are a key practical detail: you make adjustments in the field without any tools, quickly, and without the risk of dropping a spanner into the grass. The only important thing is to keep track of the orientation of the optical train during assembly, so that your adjustments remain logical and repeatable.

With an M42x0.75 (T2) thread on both sides, the tilter fits naturally between your camera and an adapter or any other accessory with the same thread. At only 11 mm tall (excluding a T2-T2 adapter), the compensator adds almost nothing to the optical train length and does not eat into focuser travel. The 78 mm clear aperture provides plenty of room even for larger imaging chips. The focal plane compensator works quietly and precisely - a proper corrective tool, not a workaround.

The T2 Tilter is a practical solution for anyone who wants to get the best out of their optical system without lengthy mechanical work on the focuser or camera. Set it up correctly, and you will never again have to choose between a sharp centre and blurred corners.

Technical specifications

Who is the TS Optics T2 Tilter for?

The T2 Tilter suits anyone who does astrophotography and struggles with uneven star sharpness across the frame. It works well with Newton telescopes, where focal plane tilt is a particularly common issue, but it is equally useful with refractors or other telescope types where the optical train includes multiple accessories.

You do not need to be an experienced astronomer to use it. The tool-free knurled screws make the adjustment straightforward, and the result - sharp stars from corner to corner - is immediately visible in your next test frame.

How to use the T2 Tilter

1. Insert the T2 Tilter into your optical train between the camera and the adapter or focuser.
2. Take a test image and check star sharpness across the full frame.
3. Identify which corner or side shows the worst blur.
4. Use the knurled screws to tilt the compensator in the appropriate direction.
5. Take another test image and repeat until stars are pinpoints across the entire field.
6. Once set, the adjustment holds securely during your imaging session.
