Problems with my canon 6D ? bands on image

[mrbirth]

Hi guys, I'm having problems with bands appearing throughout the image, even in a single frame it appears, I took the focuser apart and didn't find reflection bands. My setup is a willian optics star2 71mm with a canon 6d mod, I use uhc filter (I've tested it without, same thing) with the asi1600/nikon d5300 I don't have this problem. Single ligth and flat. Thanks.

As the problem is only with the 6D.

And the problem radiates from the middle-top of frame, the most obvious question would be:

Do you have the camera's eyelevel viewfinder blanked off ?
