Again, the endearing narrow-gauge railway 'Tertitten', here represented by the century-old locomotive 'Höland' (name is written with the German 'ö' instead of the Norwegian 'ø', as the machine is made in Germany).
Nikon Z5, Rodenstock TV-Heligon 50mm f/0.75, IR-filter B+W 093. The Heligon softens quite noticeably when used for IR, but that effect simply adds to the charm of using (or rather, abusing) this vintage X-ray lens.
