I'm still trying to get the Ha data added to this galaxy without being quite as harsh. Here's the latest. Better I think.

Beautiful work Tom!

Tom,
This is an interesting thread and it is stimulated by your great M33 image. I think that incorporating emission line data into RGB is always going to be a challenge for the astro imager. Others have stated that those taking this approach will always get critical comment on the color hue. There is also the challenge of relative intensities of the exposure sets. We can calibrate RGB pretty well (G2V, balanced fiter sets etc.). But we have little guidance when adding emission line data to RGB. Perhaps you have some insights into that?

Only other comment/question on the image (I personally like the color) would be a suggestion that the Ha saturation might be lowered a bit. I can do this on the overall image and it seems like it would be a useful consideration, only I can't do it on just the Ha like you could. My 2 cents worth...
