Today shots of a flower originating from the USA Prairie, black-eyed Susan - Rudbeckia hirta in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as in simulated bee vision using my XBV6 filter. Lens was my CERCO 94mm quartz flourite lens. Light source was sunlight. All shots were done at about f5.6.

Triptych of the above images:
This flower shows a very prominent UV bullseye pattern, I would even say it is one of the most known flowers with UV pattern, as its petals are very UV bright (around 365nm) to about the middle and its center is UV dark (aging spots on this older flower can bee seen in UV+BV), and all this gets nicely visible.
I have previously written about that flower HERE.
Stay tuned, more will follow on that fascinating subject...
