Yes that is a possibility too. If your mount is unbalanced or it shifts in balance at different angles (do you have a piggybacked scope?) or you camera filter if sticking out at an odd angle. Dragging cables.
See if you can check the balance of your rig at those angles you know you get elongated stars. It may be way off even if balanced when horizontal.
I always balance my scope at a typical imaging angle not horizontal which of course you never image at.
