Side by side, your HA on the left versus my red on the right. Ignoring the bloating that I am not sure if at this point is a result of 2200mm focal length challenging the guiding and seeing, or the same sort of issues that the IR cut resolved on my refractor. When I have some spare cash I will get the filter for the SCT and find out.
This is what I was meaning before, there is much nicer detail in your HA in the middle of the nebula, but conversely there is some obscured areas in my red channel (Which obviously covers the HA) that do not seem to appear in HA only.
