Help with horizontal banding

I'm hoping someone here can shed some light. I used APP to stack 30x300 sec light frames shot with an ASI294mm through an Ha filter and got noticeable horizontal banding. I've re-run the stacking multiple times and have the same result when I run with no calibration frames. Individual light frames look fine - I've gone through all 30 and can see no banding but when I integrate all 30 in APP, the banding is quite noticeable. For simplicity I've ran it with no change to default settings. Can anyone suggest what I might be doing wrong or if there is a setting I should be using?

Ha single   no banding
Ha only   stacked   banding

never mind, think I figured it out. the horizontal banding was an artifact introduced by USB connection. Moved all files to local hard drive in laptop and re-stacked and the issue went away. Cheers!

Great and thanks for sharing that. It happens now and again indeed and has become the usual question to a user when it's super-weird looking or indeed seemingly random interference. 🙂
