Orange coneflower - Rudbeckia fulgida in reflected deep ultraviolet photography and simulated butterfly and bee vision X

Today lab shots of a decorative summer flower which started to bloom on my balcony, Orange coneflower - Rudbeckia fulgida in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U, Jupiter-U, Saturn-U and Uranus-U deep UV filter, as well as in simulated butterfly and bee vision using my proprietary XBV filters. Lens was my CERCO 94mm quartz flourite lens. Light source was a modified Xenon flash. All shots were done at about f8.

This attractive flower shows its very prominent UV bullseye pattern, its petals have an UV dark bottom and very UV bright tips (around 365nm), invisible to us humans, and all this gets nicely visible.

Stay tuned, more will follow on that fascinating subject...
