Well, my orchids started to blossom again, so why not take a chance and try out an old friend: EL-Nikkor 5.6/80mm (black / chrome older version)
The sequence is: UV (through Baader-U), VIS (through UV/IR Cut filter), IR (through B+W 092)
and here the same sequence but showing left and right differentials (VIS-UV, VIS-IR):
No focus correction was done during the shots, using a single 400Ws adjustable Xenon flash and ND filters to balance out the exposure differences, so as to ensure an identical light direction.
And here a multispectral image by assigning UV->blue, VIS->green, IR->red and combining that into one image.
The fit is very well, thanks to the lack of focus shift, it was overlaid as is, no matching was applied.
I find that result quite interesting ... as it hardly shows focus shift, but hardly anyone seems to use it
