I continue to experiment with the modified Canon 350D. This test is with the old Lumicon Hydrogen Alpha photographic filter from the TechPan days of film. I wanted to see if I could image from my backyard with this filter and come up with anything useful. Conditions were horrible on this night with temps in the 70's, humidity in the 90's, and a waxing moon. I am happy with the results and will continue my testing. The ideal scenario is for a much more narrow band hydrogen alpha filter, but at this time none are available for inside the camera body of the Canon.
