It looks like in the center of SDSS images is another object then in the center of 2MASS images.(The two objects are swapped.)

Any ideas?Am I right that SDSS images are shifted?

Good catch TED91. To me, it also looks like the SDSS Z has multiple sources in it.

I think the image has been flipped. And so the external object changes position but the central remains the same.
