[UV] Sedum flower: Baader-U vs Jupiter-U filter for reflected UV ultraviolet photography

Again more about that new Jupiter-U filter of mine. This time it is about a yellow Sedum spathulifolium flower, that I bought at a nursery (Huben, Ladenburg, Germany)

All triptychs are presented VIS left, Baader-U middle, Jupiter-U right:

Although this one has an overall 365nm main reflection, inside that flower is some long wave (around 385nm I'd say) UV reflection visible, that only the longer wave Baader-U filter is able to reveal.

Here details of that flower...

using the Baader-U filter:

and the Jupiter-U:

Overall this interesting plant looks like this (VIS, Baader-U, Jupiter-U)

Might it be that the unusual high UV reflection of its leafs aims at protecting it from too much UV radiation? Here how that looks like in closeup (VIS / UV):

Mother nature has quite good ideas!

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