Canon 600D..
Just wonder why it is blue in color instead of red? Is that because DSLR?

Yep.

M8 is a strong emitter of oxygen, hence the blue. If you modified your camera, it will pick up the pinks and reds associated with hydrogen alpha.

Erm that's weird, mine comes through as pink red and white on my unmodded 1100D

I didn't look at the picture properly. Your right, Dunk, that's way too blue. Has this been touched up at all?

Did you use the wrong debayer matrix?

Processing.
I have a un-modded DSLR and my shots are pink and blue when saturation added

Hi Everyone thanks for your reply. I have CLS filter... not sure if that may causing the problem or maybe I used the wrong debayer matrix which I have to check my laptop later. But really thanks for everyone idea....

LP filters cast images blue and need to be rebalanced during processing.
