Just by eye it looks at least 0.2mm, more like even a whole millimetre.
The qhy-forum post I mentioned below says this is unacceptable for
a fast optics Newt like this. This might be a great part of the problem
right there.
Also, Marc, how exactly do you do a RGGB debayer. Are the settings
correct that I have entered here in the manual text box in Neb?
This is what I get when I select CIM debayer and 7.8 sq pixels 1x1:

Sounds about right. Tilt is a killer on a field. Sometime I get it right. I found to use extension tubes and keep the focuser barrel in as much as possible helps. I also use GSO 10:1 focusers.
Sorry I use CCDStack not Neb for processing but from your colors you're using the right pattern.
RG
GB
two greens, one red and one blue in that order. Two Gs are recombined in one pixel.
