That's the natural colour. It's a full spectrum camera, so even without the narrowband Ha filter it would have substantial red cast. There is just so much Ha out there that it tends to overwealm the other colours on a colour camera unless filtered out. The full spectrum Canon will capture up to five times as much Ha light as an un-modified camera due to the absence of the blue cast IR/UV filter ahead of the sensor, filteting for only narrowband Ha will further reduce the other colours.
