Imaging below a diffraction limit

Hi all,

I have been quite successfully using my 4" doublet with a reducer that combined with my camera give me 1.33" per pixel - about the diffraction limit for a 4" telescope. Now when I have a reliable mount, I was wondering if it would make sense to try imaging the native fl- it would mean slowish f/7 and 1.07 arcseconds per pixel, which unfortunately is below theoretical diffraction limit for my 4" telescope.

Does anyone have experience in imaging below the theoretical diffraction limit for their telescope?
