You're going to need really great seeing to take full advantage of that image scale.

Last night I had 1 image with a fwhm of 2.2 arc seconds. Maybe I just need to take colour subs on average seeing nights and get the Lum data on fantastic seeing nights. Though they will be rare. I have no idea how some people get the shots that they do then. Maybe I need to move the obs to a place with much better seeing to get those really pinpoint stars, or invest in AO (not that it will provide that much of an advantage)
