Could the corners also be causing the small diffraction spikes I saw around Iota Orionis?
Yes, for sure. Anything that disturbs the light path (cuts into the light path) will cause a diffraction spike.

Thanks for the insight -- that clarifies that it must be the effect of the camera adapter then.  Could the corners also be causing the small diffraction spikes I saw around Iota Orionis?
