Hi rich. totally agree too much H2 from the modded camera. The UHC-S and UV/IR filter helps lowering this. Before wasn't enough with the unmodified 350d and now it is extremely too much

digging through my old S&T and saw that image was yours. very nice Rich
I was hoping to capture it standing upwards but i didn't want to mess with my focus again. Here's a rotated version done in ps2 and zoomed in on the region.
