You know, in Japan, they have a CANON EOS 20Da that the company actually sells as an astrography camera lets in more of the IR light. Here's a link: http://www.bobatkins.com/photography/digital/eos20da.html another http://www.canon-europe.com/For_Home/Product_Finder/Cameras/Digital_SLR/eos20da/ You can also have your camera converted: http://www.burren.cx/photo/ir_conversions.html http://www.lifepixel.com/IR.htm Not cheap, but would be neat to have a dedicated IR cam. You can find tutorials on doing it yourself and some here have done that with good results. Lots of options out there, if you have a little extra cash. :)
