![]() Sorry- I couldn't resist. I took this last night- it's a compact fluorescent bulb, taken through a BG3 filter: there's a story why I did this- bear with me, there's a good punchline at the end. My Ultraphot III was free- the terms were that I had to haul the (disassembled) beast out of the warehouse. It was a gamble that paid off, because hidden in all the drawers was a full set of epi-DIC objectives, a full set of luminars, and more- plus, the scope is in perfect working condition. There was also a bunch of Schott and Kopp color glass filters, which I no idea what to do with. Since I now have a color camera, I re-discovered the glass filters and have been seeing what I can do with them: I'm thinking solar photography, but in any case when I was wandering around looking at stuff through the various filters I noticed that looking at a CFL through the BG3 filter was *really* weird. In fact, looking at *any* intense light though that filter (and only that filter- not the RG645, OG2, 5-60 or 2-60, or any of the other ones) results in the appearance of what can be described as 'sparkles', 'tiny ants', or 'light-dark dashes' crawling around the source. I made my wife look and verify that she saw it, too- I was starting to think there was something *really* wrong with my eyes- but I am convinced it's an optical illusion: I can't capture the effect with a camera. I did some digging, and the BG3 passband is restricted to only the blue cone sensitivity. So now I am *convinced* it's a biological effect, some combination of bleaching the cones and saccadic movements of the eye. I urge you to get a BG3 filter (they are reasonably cheap) and see for yourself- it's truly bizarre. |
