There was an earlier question on the diffraction pattern in the Mar 16 test image that was mainly explained by the hexagonal shape of the individual mirror segments. Today's image has similar diffraction patterns on some of the bright stars. However some of the 'redder' objects have more complicated patterns. This picture is cropped from the larger image that was released today.:
This is a composite false-color image. It appears that the diffraction pattern on the 'red' image is rotated 30 or 90 degrees compared to the blue image. Is it that the short wavelengths are affected more by the shape of the individual segments while long wavelengths are affected more by overall shape of the mirror? Or are these from two totally different sensors with different optical paths? Can anyone explain what's going on here?
Edit: I don't know if this is a clue, but this is a twitter image from NASA
It's a different sensor, but from the varying diffraction patterns, the primary mirror is clearly being rotated with respect to the starfield. It's a large angle but less than 30 degrees.
