EDIT: Thought these might be better posted at the start of the thread. I'll leave them here anyway

I noticed that the gap between the spikes is filled with either red or blue. Out of focus blue (not so evident in this shot) and out of focus red is fairly obvious,

In focus it seems that the upper pair of spikes contain blue and the lower red.

I have also attached an image of the street light across at Safeway to illustrate the sharpness of the spikes, not so evident with a short lens.

EDIT: You will notice too, that the single spike perpendicular to the bow tie is only present when focused.
