I didn't see your comment on the information from the article I provided a few posts down - I would be really interested in reading your opinion on that
The houses were not a few hundred metres away....several kilometres in fact.

I thought they pretty clearly showed how aperture influences image resolution.
(sampling between the two systems by dumb luck was almost identical)

Deep sky imaging simply has a few more layers of image abberration by looking through a tad more atmosphere, keeping the shutter open for longer and having to pan the camera....none of which reduce the effect of your starting point.

The image simply degrades even further from there.
