This is the Mistletoe (Viscum album) a parasitic plant of several tree species in the UK. It inserts it's "root" technically called a haustoria into the stem/branch of the host tree. This is a UVF image of the mistletoe haustoria and host stem. I am not a botanist so cannot ID also the various tissues here (? Birna), but an interesting result! The section was cut carefully with a scalpel. It is approx 5cm from top to bottom of the image. Technical: UVF: Nikon D850 with 105mm micro Nikkor lens. Light painted with UV "Nemo" torch, 5 seconds at f/22

I have now some Barium Sulphate that I wanted to look at, but I am surprised that it will fluoresce too. Here is an article on the fluorescent problem in Integrating Spheres with UV LEDs. https://www.gigahertz-optik.com/en-us/service-and-support/knowledge-base/fluorescence-free-radiant-flux-measurement-of-uv-leds-2/

It is sitting on the bark on a paperbark tree which also glows due to the uv light.... 3X Magnification . Single shot.

So since it finally started raining where I live, found a slime mold and read about it, now they are my new obsession. If you dont know what they are, have a look at this: https://youtu.be/GY_uMH8Xpy0 Their fluorescence disapointed me a bit, I had very high hopes considering how bright they are in the visible. However, I got some nice christmassy images! Hope you enjoy and you have holidays full of fascinating findings. UVIVF - Cheap UV light, brand unknown, with ZWB2.

A soap bubble in 10F/-12.2C air was blown onto a flat surface and illuminated from the rear with a Nemo torch. The photo was taken with an EL-Nikkor 105mm/5.6 and BG38 2mm + Zeiss T* UV blocker. Exposure was 2.5" ISO 200 F11. It would have been nice to capture this while the dendrites were growing, and this was my original intention, but they grow very fast - you need about 1/1000" to avoid blur - and the fluorescence wasn't bright enough for that. I may revisit this with some kind of additive to supply brighter fluorescence.

I just finished decanting my Sloe Gin into bottles, and thought I would see what the gin soaked sloes (fruit of Blackthorn: Prunus spinosa) would look like in UVF. Some very interesting patterns, though not sure what they mean (if anything!) Maybe sugars from the process, or mould? Technical details: UVF: Nikon D850 with 105mm micro Nikkor and 1.4X tele converter. NEMO torch, light painted, 10 seconds at f/16.

I figured I'd try out the UV Beast 365, not bad for a tight beam. Went outside with it tonight, and was surprised how snow absorbs the visual light and fluoresces things on it and in it.

Pentax 645Z with Pentax 645 A 120 macro lens and Tiffen UV Haze 2A filter. First attempt using diy modified Pentax AF540FGZ full spectrum flash with 6mm of Tangsinuo ZWB1 UG11340nm glass covering flash tube. F11 ISO400 21 seconds to allow 3 flash pops. I tried this shot earlier without flash on a moonless night. Unfortunately, there are bright lights about 1/4 mile away and they diluted the purity of the yellow. I struggled processing this image. Difficult to decide how it should look . Any tips and comments are welcome. Thanks for looking, Doug A
