Sensor and image scale
The 2.9 µm pixels pair particularly well with short to medium focal lengths. At very long focal lengths, sampling can become unnecessarily fine.
Practical note
Calculate image scale with your telescope focal length before buying. This helps determine whether sensor and optics are a good match.
