This shot is with a CLS on a full spectrum DSLR which lets a lot of Ha through so it ends up red. If you had your Nex3 full spectrum modified, it would let through a lot more red Ha.
There's no right or wrong colour, just a personal preference.

Good explanation, thanks.
Since my DSLR is unmodded, I guess I get more blue dominance over the red Ha as well.
