I was playing with some photos shot quite a while ago, and found swapping red and blue channels really make things interesting for some landscape UV photos.
Shot on a converted Nikon J5, with a 25mm f2.8 Quartz lens, U360&S8612 stack, 2mm each.

Quite amazing! I love the cemetery. Those white stones sure stand out in UV.

Cemeteries can make interesting subject matter.

You mention a 25/2.8 quartz lens. What is this lens, specifically? I have not heard of any shorter than 60mm.

Hi Clark, it is a C mount lens made by Pentax for industrial uses, it was designed to cover 1' sensor but can be used on M4/3 cameras too with blurred corner. On my J5, its equivalent focal length is close to 75mm. It is an actual quartz lens which transmits pretty well on the lower end of the spectrum, however it is not particularly sharp when used for wide spectrum UV work.
