IMHO high res deep sky imaging requires superb seeing and great guiding, as the latter literally swamps the optical resolution of most systems.

I typically get 3-4 arc sec seeing....which is around 10x worse than the resolution of a diffraction limited 360mm aperture scope.....(and 5x for a 150mm).

Hence lining up multiple fickle fingers does not say much about a systems intrinsic resolution....to me at least...but says buckets about the seeing on the night.

Not its not exemplary data, but for 50 minutes under a 1st quarter moon from the 'burbs.... I can live with it
