I am not changing anything in my system except the NB filters and they are changing from 12nm to 6nm, so yes it will be a valid test I guess as the current Astronomiks in use show all ok.

I'm just going to finish off my current project (hopefully next New Moon period ) first and then I will put the new NB filters in and shoot something
