Is this normal to have vignetting in one corner like this? It's pointed at my ceiling. The second image is after me spinning the entire train where the Feather Touch focuser connects to the telescope and shows the vignetting moved as a result of the spin. Stellarvue 102mm Carbon Fiber Raptor,  Stellarvue Large Chip Flattener, Feathertouch Focuser, ZWO filter wheel and a ZWO ASI071 camera.

That's not normal.  Something is tilted / misaligned.

Look for a light leak.

+1.  That too.

I've removed everything and can't find the source. The only thing I'm thinking is possibly the flattener. Unfortunately I have no way to test that since I can't connect the camera without it,

Call Stellarvue and talk to Vic.  Email this the above pic.

Ok, I feel like a moron! LOL It was slightly pointed to recessed lighting in the ceiling. When I pointed it at a wall 50' away everything looks perfect. Ugh. There's 2 hours of my life I can never get back  BUT, lesson learned. At least I got to clean all my optics.

"There's 2 hours of my life I can never get back"  but you learned something.
