Martin.
The QHY8 is a one shot colour camera, but having said that it does work OK with an Ha filter, so that would be the initial suggestion. You will need longer subs though, something like 10 - 15 minutes each. And given my past experience with a QHY8 sized sensor, it will need to be 2", not 1.25", sorry.
The filter will not really help with the "band of light" though, as Peter said, it will be a reflection from within your imaging train somewhere. You are not alone with this issue, so track down some older posts where others have suffered in a similar fashion and find out how they resolved it.
