Product description

ASKAR Deluxe Tilting Adapter for astrophotography

Larger sensors with higher resolution sometimes show distorted stars at the edge of the image field, even with corrected optics. The cause is a skewed image field, the sensor is not exactly aligned with the optical axis. This error can be corrected with a tilting adapter. Simple tilting adapters use tension and compression screws, which makes adapting very complicated and imprecise, and also changes the distance of the camera sensor, resulting in a loss of quality.

ASKAR Tilter

The ASKAR Focal Plane Adjuster uses a better system where the tilt angle is set precisely without changing the relative distance to the camera sensor. This means that the optimum distance is always maintained and you can see the improvement in the star image almost immediately.

The ASKAR Focal Plane Adjuster is very easy to operate using two easily accessible clamping levers. Once fixed, the tilting position is reliably maintained. You can restore the tilting position at any time using a precise scale.
