Hey nice job.

With narrowband you have to boost the red as green can be dominant (Ha is almost always the strongest signal) and O111 (blue) is next strongest usually (not always).

So you need to use curves to bolster up the red harder otherwise your narrowband images will be blue/green in colour only.

You can do this using layers or you can assign the red to a channel in photoshop and then boost that channel - whatever you like.

Greg.
