This orchid has a very specific UV pattern, its petals are very UV dark, but its lower petal lip has on the lower center a very UV bright spot as well as on its center "nose" formation an UV reflecting spot and all this gets nicely visible, also with this Lyman Alpha I f2.8/200mm mirror only lens.
I have written about the Nye Lyman-Alpha lenses previously HERE and about this Orchid HERE
Stay tuned, more will follow on that fascinating subject...
