can't remove noise

Hi
My first go at st so please be patient:)
I'm having great difficulty getting noise removed from my dss fits file. I've followed many YouTube tutorials and I'm beginning to wonder whether the stack is at fault:

autodev really messes up the image and I can't retrieve it. Using dev is a little better but although I can see some detail, the noise reduction is poor.
Maybe it is the iso speed in camera:
nikon d40 at iso 800 then 12 or so light frames at 10-20 seconds with dark, bias and flat frames which *seem* to have worked but...
Any help especially if someone could check the fits file and comments on iso in camera before I spend any more time would be most gratefully recieved.
TIA
