Sensor Tilt
Turn focus differences into a correction.
Enter focus offsets measured across the sensor. The plane model shows the tilt magnitude and the equivalent adjustment at your tilt plate.
Measurements
Sensor and focus plane
Positive means the right or bottom edge focuses farther away; negative reverses that direction.

Plane tilt and correction
Combined tilt is 2.39 arcmin; right side and bottom side are farther from the reference focus.

Model
θx = atan(Δx / width), θy = atan(Δy / height), and combined tilt = atan(√(tan²θx + tan²θy)).
This is a geometric plane estimate. Focus measurements can also include field curvature, optical aberration, sag, seeing, and measurement noise. Confirm corrections with repeated exposures.
