Fringe killer and reflection nebula

[astrosatch]

Greetings!

 

What would happen if I use fringe killer and image reflection nebula like M45? I would like to reduce blue halo around stars but I'm not sure If this affects (and how much) reflection nebula because it's blue. 

 

Thanks

What are you using to image with? Could you stop it down?

I use evostar ed72 which is doublet, but blue halo remains around stars. I was thinking that filter should reduce halo but not entirely dim the blueish nebula.

This is the transmission of this filter. In what wavelenght does reflection nebula shine? Or from where in blue specter does it start to fade?

thanks for info
