Howdy Jeff, with my camera I ordered the clear AR coated glass option rather then an IR cut filter that cuts in after the Ha line, as I want to dabble in IR photography. Ive also purchased an IR pass filter that blocks all visible light Here is an example of its use.
Its Planetary nebula MZ3, where the red has been assigned to the IR image, grenn to the red, and blue to the green. Its interesting how MZ3's central star appears yellow whereas no others do
