Here more shots of that decorative Three-leaved Coneflower - Rudbeckia triloba in reflected ultraviolet using Baader-U filter and in simulated bee vision using my XBV6 filter. Lens was a 55mm Dialyte lens. Light source was sunlight. All shots were done at about f8.

Triptych of the above images:
This attractive flower has a very specific UV pattern, its petals are bright on the petal tips (reflecting around 365nm), have a UV dark bullseye pattern invisible to us humans and also the flower center is quite UV dark, and all this gets nicely visible.
I have previously written about that flower HERE.
Stay tuned, more will follow on that fascinating subject...
