Hi guys, just going through my images taken yesterday. I noticed one corner had badly distorted stars. Is this due to field curvature or from tilt of the focuser. The new camera (Qhy9 with 2" filterwheel) is on the heavier side that may have contributed to the tilt. Is there a solution to this without having to resort to a more expensive focuser?

I've uploaded 100% crop of the corner in question and the full image (with IIS compression) for your analysis.

Thanks
Tony
