So long as you don't go pixel peeping at star shapes, it is a very lovely image. Beautiful depth and colour, and nicely processed.

Would love to see a retake once you've sorted out the flexure problem.

We had a vaguely similar problem with the Apogee CG16M, ten position filter wheel, and off axis guider all hanging off the focuser on the PlaneWave. Many kilos altogether. It would flex as the scope tracked in RA. At 3.5m focal length the tilt wasn't an issue, but the whole thing would go out of focus. We fixed it with a long hinged strut to support the camera as it tracked in RA.
