He is imaging at an image scale of 0.4"/pix, his software is telling him the max FWHM (of that star with square around it) in the x direction, is 2.94pix, so we have 2.94 X 0.4 = 1.176" and a FWHM in the y direction of 2.58pix or 2.58 X 0.4 = 1.032"
so suggests, essentially pretty close to 1 arc sec seeing...very cool
Great shot Col
