Orb Crescent Trio and Orb Veils with Tails

Photo date: September 29, 2015. Photographer: Mark Mahin.

The photo below was taken while photographing ordinary drops of pure, clean water falling against a dark featureless background.  We see at the top three of the inexplicable objects I call orb crescents (for 49 other photos of such objects, see here). Near the bottom is one of the strange objects I call orb veils (67 other such photos are here).  This one is highly unusual, not only because of its orange color, but also because of its tail-like structure.

On the same day I took the photo below, which shows more orb crescents, and another orb veil with a tail-like end. What is that weird rainbow-like thing in front of the veil? And what is that "tilted cross" shape we see inside the orb veil?
