I have modified a Sony Nex 6 so I will find out myself how this goes.

Thanks Greg for advice. I assume this wouldn't effect the modded camera's sensitivity to the Ha. Just shifting and compressing the colour display levels rather than using an Original White Balance (OWB) filter - which i have but didn't want to use in order to capture more Ha wavelengths.
