Not at all Paul.
But I think some clarification is needed.
Small aperture, iosplanic cells can and do drift over several arc sec.
Clever software like .Avistack and Registax follow that movement, giving the illusion of sub-arc second seeing.
Take a simultaneous deep sky image covering say, 1/4 a degree of sky you'll see the drift..or seeing induced... datum distributes around a bell curve, you will see also over some minutes, a totally different figure.
A simple measurement of (deep sky) FWHM's verify this...and on casual inspection, your (posted) deep sky images are, sorry to say, on a par with everyone else's...ie around 2 arc sec.
I'm not having a go at you...just trying to point out that "seeing" is not that simple.
P.S.
Still not convinced? A simple,
non-aligned sum, of say 2-300 planetary images should also prove the point
