I see very few infrared images and discussion here on the Mu43, and I wonder why that is. I have yet to take an IR image with my Olympii (still waiting for filters), but that doesn't stop me from admiring and playing with IR images. I know that there are a couple of you out there, because someone has exchanged info with me recently (although I can't remember who). I would certainly love to see a subforum dedicated to IR and UV (I'm going to start playing with UV also). I work with a lot of IR and UV imagers (sensors/detectors) at NASA/GSFC and there is no reason why I can't mix business with pleasure along these lines (although I have much to learn).
