It has a tilting plate to align the camera to the secondary. I don't think any weight from the camera is pulling on the mirror. Either way, since this photo, I recollimated using a shopping bag full of beans to simulate the weight of my imaging train (AO, ONAG, QSI683, SX Lodestar), approx 1kg (1.5kg - 0.5kg for the howie glatter laser).
If the tilting plate was not strong enough, or the mirror was loaded, I would expect the collimation to change as the altitude of the scope changed. It measured the same throughout the latest imaging session.
