Its got everything going for it but colour balance and perhaps your Ha blending technique.

Firstly with modded DSLRs you need a custom white balance. Get an 18% photographic grey card and take a photo of it at midday on a sunny day and set the image as the default custom white balance. Do it once and you are set from thereon out.

Now your images will come out of the camera without the infrared red biased images and will look more like normal RGB.

Now you can do that after the fact if you shot using RAW mode files.

Play with your custom white balance to get rid of the excessive red bias.

Or you can do it with Photoshop and curves hitting the red curves hard probably with an S shaped curve. Straighten the last 1/4 of the curve so you don't blow out the highlights.

ha blending is another subject and various ways to do it. As a layer, delete green and blue channel so its only showing in red then set it to lighten mode is one "simple" way. Control the amount using the opacity slider. Screen mode also works but will be more savage and needs to be toned down more with the opacity slider.
