A DSLR Camera modification for Astrophotography consist of the hydrogen alpha wavelength bandpass transmission increase at 656nm. The original UV/IR Blocking filter present on stock DSLR Cameras only allows over 25% transmission of h-alpha emissions. An Astro-Converted DSLR Camera is about 4 times more sensitive to the deep reddish nebulae structure tones. H-alpha objects/sections are also present in all the other galaxies besides the Milky Way. The hydrogen element is present in the entire universe, and many emission nebulae visible on the night sky and the sun, emanate hydrogen alpha emissions.
