It looks like you could have pointed your lens directly into the light of the full moon. (Remeber light travels in straight lines) This has allowed the light to bounce around the mirrors inside your camera and then diectly onto your 'film plane' causing the lens flare effect. A smaller apperture ie f.22 would have enhanced this further and possibly picked up on the 'three moons' (2 mirrors + original). Try adjusting the angle slightly so the light is bounced at the opposite angle and not so directly. However with an orb at such a distance, this is not so easily achieved.
