  As Gianluca correctly states, the PSF size (by using this instrument)
is dominated by tracking accuracy, rather than the seeing (and some may
suffer from focusing errors).

  We use 3x3 binning (3arcsec/pixel) for most of our work with LX-200.
Our typical overall FWHM is a few times this superpixel.  Observers under
far better seeing and with more accurate focusing (and more reliable
tracking) will suffer more greatly than we experience.
