Here are a couple of typical responses for my setup (they differ by less than +-1% and are flat within +-2% . I suspect the dip in the middle is due to slight inaccuracies in the removal of the reference star H alpha profile rather than a real effect. (The graph is 1360 wide compared with the camera 1391 so just 31 pixels trimmed off somewhere)

Cheers
