Well, here it is what I was eagerly looking for, the first sub 325nm reflection recorded in deep UV. This relates to my previous posting about reflected deep(er) UV recording with the effective peaks: 375nm, 365nm, 350nm, 325nm. But today that result takes it even deeper, to the 300 - 325nm sub UV band.

The UV image(s) here also uses my standardized false UV color normal + high intensity palette:
Bidens ferulifolia in 300-325nm UV using a special bandpass filter:
I had to pull back the predominant green and enhance the blue channel to make it visible. But it is there and it can be recorded.
That turquoise color was the last color I was missing for my standardized false UV color palette, that I have shown above.
Just for comparison, following the visual (VIS) image and the UV image using my Baader-U filter:

And a triptych as an overview image:
Stay tuned, more will follow on that fascinating subject...
