Normalization failing when trying to stack two integrations

Before i sold my Qhy163c, i took a data set of the Iris nebula. I took 2 data sets (hundreds of subs) and stacked them both together in a single integration. I then sold the camera, and have since borrowed a friend's CCD, a Qhy9m. I took a data set with it and made a stack, but when i try to stack the 2 stacks together, it fails at Normalization. 

I've tried all different settings, Regular and Advanced, and even setting the method to None, which i assumed would skip Normalization altogether and let me progress to Integration, but it still fails. 

I've attached links to the 2 stacks below. Assuming i'm not doing something stupid, i hope it helps identify a bug of some sort. 

All the best,

Hi there, yes that is going to be improved, but for now it's not possible to normalize narrowband data with broadband data, one is mono and the other is well.. broadband. 🙂 So you need to process those two independant of each other (you can for instance split the RGB channels and then load those in again and process).
