Phosphor

@Stone Cold Steve Tuna, It took a lot of practice to get here and I still need more practice. 

Focusing ultraviolet light is almost an art for a couple reasons: Autofocus doesn't work in UV and there's just not much light to work with thanks to atmospheric absorption and scatter. Even on a bright sunny day, the ISO will be around 3200 and shutter at 1/30s with a very fast lens.

 I usually take 3 shots of the same subject and pick the best one. Sometimes I'll have to reshoot if the focus is soft.

I can talk all day about this subject  

I would probably attend a lecture from you for it honestly

I think you managed to capture them all quite well.
