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...
