But just check that the dark looks like the one on ZWOs website that JA pointed out. I'm surprised about the amp glow though. I thought these cameras had circuitry to reduce that - maybe I'm wrong?

Thanks for confirming that Chris.
I had seen those reference frames on the ZWO site and that's what freaked me out a bit - they are pitch black. As JA pointed out, very different to mine, but I didn't realize at the time that the ASIAir app was automatically stretching the images.
The amp glow is well documented for that camera - I knew about it before purchasing with the understanding that the artifact could be easily removed with dark frames (which is why I was getting nervous thinking that my dark frames were faulty).
Anyway, I think I am all good now - thanks again
